Cell Biology Final Exam Flashcards
This is cell biology at the molecular level. Additional learning objectives will introduce challenges to your analytical and intuitive skills by analyzing figures and data in the laboratory in small group interactions. Lastly, a learning objective addressing introduction to quantitative skills will be covered in several laboratory topics. A brief outline for the course is listed below. Syllabus details will be posted on our Web site on a weekly basis. We will not be locked into a rigid time frame for a topic so we will sometimes gauge our progress using the syllabus as a guide. Sometimes we may have to skip or spend extra time on a topic. We will have a couple of 'exam review days'instead of lecture - this way , we have the room and time provided otherwise, logistics are tricky.

Reading assignments are highly recommended ; this is such a well written book. If there is outside reading it will be provided by either posting material on reserve at the library or as class handouts or in our Biol. Although we will primarily cover animal cell biology, plant, bacterial,and viral systems will also be explored as important examples. We will occasionally work out problems at the end of the chapter or from other sources. We will also see 4 or 5 films to get a visual of a lecture topic. Lectures will focus on mechanisms- how things work. Vocabulary: Click on link for Biol.
Biology 1 Final Exam Review
I strongly recommend ongoing construction of a vocabulary deck if you are unfamilar with terms used in lecture. The old-fashioned 'Flash Card' concept is time honored! It is assumed that the fundamentals of animal and plant biology are a part of your background the first two core courses in our biology curriculum. Organic chemistry Chemistry A , past or current enrollment , is also required. Course Policies: School closing s : Exams that are postponed due to the University closure bad weather or a science building evacuation will be rescheduled for the next class meeting. Assigned number: Each student will receive an assigned number to use for identification for any e. Please refrain from munching on noisy snacks during lecture. Also, please do not bring children to class. Emergency situations will happen and we can deal with these on a case by case basis if discussed prior to lecture. Incompletes: Incomplete grades will be given only to students unable to complete the required course work because of a verifiable crisis and at the discretion of the instructor.
Biology final Exam
The College of Arts and Sciences has an approved contract form dealing with incompletes; see me for information if this applies to your situation. Incompletes will NOT be given for bad grades. Exam issuance and make-ups: No exam will be handed out to a student after the first person hands in a exam. No extra time will be given to any student coming late to the exam. Please remove caps or hats during the exam. Each student may makeup one exam if you take the makeup exam within one lecture of the scheduled exam date by calling my office or email pwanda siue. If you had an emergency that prevents this, please discuss this with Dr. Wanda as soon as possible. Make-up exams usually have different questions and primarily be in an essay format. There will be NO make -up exam for the optional final exam or quizzes. Attendance: Class attendance in lecture is required.
Molecular and Cell Biology (MCELLBI)
Attendance will be taken during the first week of class. Students who do not attend the first week of class will be removed from the class list. Since the exams cover a big portion of lecture material and class handouts, the easiest way to earn a good grade is to come to class and to have a good set of lecture notes. The textbook will serve both as a reference source for the material covered in lecture and as a direct source of exam questions. I can offer study suggestions but if you do not apply yourself to the material, chances of success are slim. The instructor assumes that all students are attending class regularly , doing the assigned reading , using the Web site and that they are therefore fully informed of any announcements made in class or posted on the course Web site.

Cell Biology Winter 1995
Nonpermeable d. None of the above. A cell membrane is a thin layer of molecules that surrounds the cell. Its function is to allow certain materials to enter the cell, yet, keep harmful materials out. In order to do this, the cell controls which substances can enter the cell through the membrane. The cell membrane is selectively permeable or semipermeable , which means that certain molecules, such as oxygen and water, are permitted to enter the cell.
Cell Biology 2382 Final Exam
Molecules that are not recognized as helpful are not able to pass through the membrane. Incorrect answer. Please choose another answer. A cell uses which of the following to accelerate chemical reactions enabling its metabolic machinery to operate? Centrasome c. Golgi apparatus d. Enzymes Enzymes are catalysts, chemicals that speed up chemical reactions. The conditions inside most cells do not allow reactions to proceed quickly enough to support life. For example, temperatures inside organisms are not hot enough for chemical reactions to take place quickly. Enzymes increase the rates of biological chemical reactions. Which of the following is not part of the metabolic sequence? Photosynthesis c. Hydoplasm d.
Humboldt State University-Cell Biology Final Exam
Digestion Inside cells, sequences of chemical reactions take place to support life. These sequences are known as metabolic pathways. Photosynthesis, respiration, and digestion are all examples of metabolic pathways, or sequences. Photosynthesis is the metabolic pathway that produces oxygen and glucose in organisms with chlorophyll. Respiration breaks down molecules called ATP for cells to use as energy. Digestion breaks down food to be used to make energy in the form of ATP. Hydroplasm is not a known metabolic sequence. Which of the following are NOT organelles found in animal cells? Nucleus and golgi apparatus b. Cellular membrane and cytoplasm c. Mitochondria and ribosomes d. Chloroplast and central vacuole Chloroplasts and central vacuole are important organelles in plant cells.

Genes are found on chromosomes. Double c. Quadruple d. The DNA molecule looks like a twisted ladder and is referred to as a double helix. Each nucleotide contains a sugar molecule and a phosphate group, along with a nitrogen base. Genes are located within the cytoplasm of the cell. Hydrochloric acid c. Ribonucleic acid d.
Bio 101 lab final quizlet
In the ribosome, the information coded onto messenger RNA is used to make proteins. When sexual reproduction occurs in multicellular organisms, a process takes place before cells fuse whereby a cell is left with half of its chromosomes, enabling the creation of a cell with a characteristic chromosome number. What is this process called? Osmosis c. Anabolism d. Differentiation During meiosis, gametes sex cells are formed by reducing the number of chromosomes found in somatic body cells by one half.
Cell Biology Final Exam Test --- Dr. Johnson Fall 2009 (UAPB)
This occurs so that when two gametes, one from each parent, fuse together, the embryo will contain the correct number of chromosomes. Without meiosis, offspring cells would contain double the number of chromosomes of normal adults and they would not be viable. Which of the following represents the largest group of biological classification? Kingdom c. Class d. Genus Biology uses a system of classification to group organisms together based on their characteristics.
Cell Bio 2382 - Final Exam Notes.docx
The levels of classification, from largest most inclusive to smallest most specific , include domain, kingdom, phylum, class, order, family, genus, species. There are two types of cells, eukaryotic and prokaryotic. Which of the following cellular structures are found in both types of cell? Prokaryotic cells are found in bacteria and their structure is much more simple than eukaryotic cells. Prokaryotic cells have a few simple cellular structures such as a nucleoid region, ribosomes, and a plasma membrane. Eukaryotic cells have more highly developed cellular structures including organelles that support the function of the cell. Golgi apparatus and mitochondria are found in eukaryotic cells.
Molecular cell biology final exam
Chloroplasts are found in eukaryotic cells that contain chlorophyll, such as plants. What it is the name given to specialized structures within cells responsible for carrying out specific functions such as providing energy and producing hormones? Mitiosis c. Archaeans d. Organelles Organelles are specialized structures in cells that support the cellular functions. For example, mitochondria are organelles that synthesize energy; ribosomes synthesize protein; chloroplasts convert sunlight, carbon dioxide and water into oxygen and sugar. Internal complexity c. Size d. Ecological relationships Unicellular organisms are very small compared to most multicellular organisms. If they were as large as a multicellular organism, their surface area to volume ratio would be too low to support life. Staying small gives unicellular organisms a high surface area to volume ratio. Larger cells have less surface area compared to their volume. Molecules move into the cell, out of the cell and through the cell slowly through the cell membrane.

The literature suggests that exams and other high-stakes assessments tend to drive student learning in the classroom Tobias, ; Tobias and Raphael, The data are persuasive, and upon reflection, most experienced instructors would concede this is very likely to be true. No matter how much time and energy a professor puts into challenging students to think critically, no matter how much we implore them to think like a scientist, if the exams they face do not test higher-level thinking and problem solving, students are not likely to master the material Traub and MacRury, Students perceive that the information on our high-stakes assessments is what we truly value Entwistle and Entwistle, , and the exam format itself can change how students study and approach problem solving. As instructors, our exams and other assessments certainly also impact us. We genuinely want our students to learn things that Benjamin Bloom would have considered higher level, but we struggle with how to assess it.
Biology final exam
Consider this learning goal: to think like a scientist and be able to adaptively negotiate a question or problem. It is an appropriate learning goal, but if we attempt to align it with our traditional assessments quizzes, exams, homework, etc. In mentoring our graduate students, we tend to teach with a questioning style much like that of Socrates Stumpf, We interact one-on-one and ask questions to evaluate as well as to determine how to best guide our students.

It was used to assess higher-level thinking, while at the same time allowing verbalization to better impact learning. The assessment was predicted to allow students to also participate in a metacognitive process as they grappled with the topic and how to explain it to others Baddeley and Hitch, The buy-in from students created a novel culture of learning outside the classroom driven by this high-stakes assessment DiCarlo, and appears to have a lasting impact on student learning. It is the second in a core two-semester introductory biology sequence for science majors. All students were enrolled at MSU, and participant consent was obtained while students were enrolled in the course. The registrar provided ACT science and composite scores and demographic data for of the students who participated. With the approval of MSU-IRB IRB , student data were also collected for longitudinal tracking and comparison purposes from all 21, students who completed select upper-level science courses at MSU from to The VF process is structured to incentivize students to participate with high reward and to decrease anxiety by having no penalty.

Students may retake the VF a number of times. If they do not pass, they take the written final exam. In addition to the method listed below and in greater detail in the Supplemental Material , we have made additional resources available, including audio and video recordings of students taking the VF, on the public VF website www. VF Protocol During the exam process, instructors keep notes of questions asked and student errors that occur Figure 1.
Cell biology exam 3 review
False- because enzymes enhance the rate but do not change the equilibrium point of a reaction, a reaction will always occur in the absence of the enzyme, though often at a minuscule rate. Moreover, competing reactions may use up the substrate more quickly, thus further impeding the desired reaction. Thus, in practical terms, without an enzyme, some reactions may never occur to an appreciable extent. High-energy electrons are more easily transferred, i. This second reaction releases almost the same amount of energy as the initial hydrolysis of ATP, thereby approximately doubling the energy yield. A partially oxidized carbon atom has a smaller diameter than a more reduced one. Oxidation is the removal of electrons, which reduces the diameter of the carbon atom.
Biology 101 Quizlet Chapter 4
Some activated carrier molecules can transfer energy and chemical groups True. The rule that oxidations release energy, whereas reductions require energy input, applies to all chemical reactions, not just those that occur in living cells. Living cells have selected a particular kind of chemistry in which most oxidations are energy-releasing events; under different conditions, however, such as in a hydrogen-containing atmosphere, reductions would be energy-releasing events. Cold-blooded animals have an energetic disadvantage because they give less heat to the environment than warm-blooded animals do. This slows their ability to make ordered macromolecules. All cells, including those of cold- and warm-blooded animals, radiate comparable amounts of heat as a consequence of their metabolic reactions.

If Y is removed by a second reaction, more X is converted to Y so that the ratio of X to Y remains constant. The active site of an enzyme usually occupies only a small fraction of its surface True. Only a few amino acid side chains contribute to the active site. The rest of the protein is required to maintain the polypeptide chain in the correct position, provide additional binding sites for regulatory purposes, and localize the protein in the cell.
Cell Bio- Exam 1
Catalysis by some enzymes involves the formation of a covalent bond between an amino acid side chain and a substrate molecule True. Some enzymes form covalent intermediates with their substrates; however, in all cases the enzyme is restored to its original structure after the reaction. Alpha and Beta sheet can contain up to five strands, but no more False. The specificity of an antibody molecule is contained exclusively in loops on the surface of the folded light-chain domain. It is true that the specificity of an antibody molecule is exclusively contained in loops on its surface; however, these loops are contributed by both the folded light- and heavy-chain domains.
Cell Biology
Allosteric enzymes have two or more binding sites True. Allosteric enzymes generally bind one or more molecules that function as regulators at sites that are distinct from the active site. The possible linear arrangements of amino acids are so vast that new proteins almost never evolve by alteration of old ones False. The possible linear arrangements of amino acids that lead to a stably folded protein domain are so few that most new proteins evolve by alteration of old ones Noncovalent bonds are too weak to influence the three-dimensional structure of macromolecules. Noncovalent bonds are a major contributor to the three-dimensional structure of macromolecules.
