Explain the difference between acids and bases and be able to identify an acid or base by its position on the pH scale. Also explain how a buffer affects the pH of a solution. Explain the role of condensation and hydrolysis reactions in the formation and break down of organic compounds (notes and figure 6.18 on pg 159 of your book) **Know the different kinds of organic compounds (carbohydrates, proteins, lipids, and nucleic acids) and functions and properties of each (Study the handout of the table of organic compounds you received in class)** Describe the difference between an unsaturated fatty acid and a saturated fatty acid Describe what an enzyme is and be able to describe their role in a chemical reaction Describe what activation energy is and explain the relationship between the activation energy and enzymes and why it is important to an organism. Explain the relationship between the active site of an enzyme and its substrate (see figure 6.23 on pg 162) List the factors that determine the rate at which enzymes work. Describe what happens to the active site of an enzyme under extreme temperatures and pH and explain how this affects the activity of the enzyme.
