Understanding how these molecules carry out their roles will help you understand how your body functions from day to day. You will have a chance to revisit these questions later, applying concepts and skills you have learned in the chapter. The molecules of living things exhibit a very wide range of chemical and physical properties. One of the most important properties of a biological substance is solubility. In this activity, you will examine the solubility and physical state of some common biological substances. Equipment and Materials: balance; test tubes; stirring rods; mL beaker; distilled water; hot water; samples such as starch, glucose, sucrose, cellulose fibre, egg albumin, beeswax, butter, olive oil, and table salt 1.

Measure 0. Add each weighed sample to 10 mL of distilled water in a labelled test tube. Stir each mixture. Fill the beaker with hot water from the tap. You will use this as a water bath. Place the test tubes in the water bath, and stir each mixture vigorously for 1 min. NEL skills handbook A2. Record the state of each substance solid or liquid and its solubility. How do you think the solubility of a substance affects its chemical reactivity in solution? Suggest reasons why some substances dissolve in water, while others do not. How do you think the size of a molecule affects its solubility? How might the properties of wax be useful for living things?

Which of the substances you tested formed a suspension, rather than a solution, in water? How do you know? Do you think blood is an example of a solution, a suspension, or both? Consider milk and other suspensions in nature that contain suspended proteins and fats. How do they differ from solutions and why might suspensions be particularly valuable for living things? You will begin to understand how everything is uniquely adapted to provide a specific structure and function. You will soon see that the properties of life stem from a hierarchical arrangement of chemical parts. Matter makes up everything in the universe, including all living organisms. Matter is composed of elements. An element is a pure substance that cannot be broken down into simpler substances using ordinary chemical or physical techniques.
Section 8.2 Photosynthesis An Overview Answer Key
The smallest particle of an element is an atom. Elements differ from one another in their atomic structure. Atoms often bind to each other chemically in fixed numbers and ratios to form molecules. For example, the oxygen gas we breathe is formed from the chemical combination of two oxygen atoms. A chemical compound is a stable combination of different elements that are held together by chemical bonds. In the study of biology, you will encounter a great variety of chemical compounds.

The chemistry of life inside a cell is complex in terms of the sizes and shapes of molecules and their functions in chemical reactions. Even so, all organic carboncontaining compounds in living organisms are composed primarily of carbon, C; hydrogen, H; and oxygen, O. As well, they often include nitrogen, N. These elements often occur as ions or in inorganic compounds within living organisms. Iodine, I, and iron, Fe, are examples of trace elements.
Biology 8.2 Photosynthesis An Overview Answer Key
A deficiency in any trace element can lead to health problems. Table 1 Percentage Composition of Selected Elements in Living and Non-living Things Seawater oxygen hydrogen chlorine sodium magnesium sulfur potassium calcium carbon silicon nitrogen strontium An atom is composed of three subatomic particles: protons, neutrons, and electrons.
Bozeman cellular respiration worksheet
The number of protons in an atom defines its elemental identity Figure 1. Protons and neutrons are located in the nucleus. Electrons are located in the region surrounding the nucleus. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. An atom has no net charge because the number of protons is equal to the number of electrons. The atomic number of an element is equal to the number of protons in the element. For example, carbon has an atomic number of 6, so all carbon atoms have 6 protons in their nucleus. A carbon atom also has 6 electrons.
Vollhardt Organic Chemistry Structure Function 6th txtbk.PDF
The number of neutrons in the nucleus can vary, as you will learn later in this section. The mass number of an atom is the total number of protons and neutrons in the nucleus. Electrons are not included in this number because the mass of an electron is negligible compared with the mass of a proton or neutron. The mass of an atom is therefore determined by the number of protons and neutrons it contains.
