Monkemeier November 9, 2009 Biology Unit: Cellular Energetics (Chapters 9 and 10) Chapter 9: Cellular Respiration Practice Test 1. Organisms that can manufacture their own chemical energy sources are called _____________. ________________________________________ 2. ________ depend on energy stored in chemical bonds by autotrophs for their food energy. ________________________________________ 3. Simple molecules are further broken down in cells in a process called _________, during which energy stored in their chemical bonds is used to power the production of ATP. ________________________________________ 4. In glycolysis, a major portion of the energy remains in the final product, which is called ________. ________________________________________ 5. For further derivation of energy, aerobic cells must convert pyruvate into acetyl-CoA by stripping off a C0 2 molecule. This process is known as ___________. ________________________________________ 6. Because the chemical formation of ATP is driven by a diffusion force similar to osmosis, this process is referred to as ___________. ________________________________________ 7. The amino acids must be first __________ before they can be used in catabolic reactions. ________________________________________
