Biology Test #2 Name___________________________________ Chapters 6-8 I. True/False: Mark T for true, F for false and leave value judgments blank (1). _____1. All organisms release heat during their metabolic processes. _____ 2. An example of kinetic energy is a thoroughbred horse racing around the track. _____ 3. Glycolysis occurs in the mitochondria of cells. _____ 4. Since humans cannot photosynthesize but can undergo cellular respiration, photosynthesis is not as important a biochemical pathway as respiration. _____ 5. The Krebs Cycle makes use of the co-enzymes NAD and FAD. _____ 6. The organelle that is active in ATP synthesis is the mitochondrion. _____ 7. The overall chemical pathway of photosynthesis is an example of an endergonic reaction. _____ 8. All enzymes will operate best at a pH of 8. _____ 9. Anaerobic organisms only recover 2 ATP during fermentation of glucose. _____10. Wavelengths of light absorbed by chlorophylls a and b include those wavelengths in the green range. _____11. The light independent reaction of photosynthesis follows the light dependent reaction. _____12. An enzyme is completely used up during a chemical reaction. _____13. Competitive inhibition occurs between substrate and product at an allosteric site. _____14. Desert plants use the same type of photosynthesis as plants that grow in the Ozarks during the spring and fall months. _____15. During carbon dioxide fixation, carbon dioxide joins with oxaloacetate. _____ 16. Exergonic reactions require an input of energy to form a more energy rich product. _____17. Overall, the oxidation of glucose into ATP has an efficiency percentage of 39%. PDF created with FinePrint pdfFactory trial version

_____18. The first product of the Calvin Cycle in CAM plants is PGAL, a 3 Carbon molecule. _____19. Enzymes lower the energy of activation of a reaction by binding the substrate in the Enzyme-Substrate complex. _____20. Non-competitive inhibition takes place on allosteric sites when a substance such as cyanide binds with a portion of the enzyme other than the active site. II. Multiple/Choice: Choose the best response to the following. _____1. Light energy that strikes a pigment can be: a. absorbed b. reflected c. transmitted d. all of the above.
