BIOD 171 MODULE 2 EXAM 28 QUESTIONS AND CORRECT ANSWERS 2023. 1. True or False: Metabolism is a controlled set of biochemical reactions that occur in living organisms in to maintain life: True 2. T/F: Enzymes are polysaccharides that catalyze chemical reactions: False (enzymes are proteins) 3. What are usually metal ions and assists enzyme during the catalysis reaction?: Cofactors 4. Define catabolism: The process of breaking down larger molecules into useful energy sources. 5. Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell?: The anabolic process would be active as it is involved in the building up of small complexes into larger complexes 6. Describe energy transfer process relative to both ATP and ADP: ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a phosphate group. Thus ATP can be reduced (ATP-ADP+Pi) while ADP can be built into ATP (ADP+Pi-ATP) 7. An organism that derives its energy (generates ATP) from photons of light is called: Phototrophic microorganism 8. An organism that derives its energy by removing electrons from elemental sulfur would be classified as: Lithotroph 9. A reactive intermediate would be present in which phosphorylation process: ? 10. The chemical compound losing the phosphate group is referred to as the: phosphorylated reactive intermediate 11. The catabolism of a single molecule of glucose goes through what 3 distinct transitions: Glycolysis, Fermentation or Respiration, then the ETC- electron transport chain 12. What is the most energetic transition in the catabolism of glucose?: The electron transport chain yields 34 ATP while both glycolysis and fermentation (or respiration) each yield only 2 ATP 13. Identify the reactants o
