BIOD 171 ESSENTIAL MICROBIOLOGY MODULE 2 EXAM ACTUAL 2024 UPDATE EXAM WITH CORRECT ANSQWERS VERIFIED EXAM GRADED A+ True or False: Metabolism is a controlled set of biochemical reactions that occur in living organisms in order to maintain life. Correct! True False True or False: Enzymes are polysaccharides that catalyze chemical reactions. True Correct! False Enzymes are proteins that catalyze chemical reactions. What is a cofactor? And give a general example. Your Answer: A cofactor is a chemical component that helps enzymes during catabalilsm. They are usually metal ions. A cofactor is a small chemical component that assists an enzyme during the catalysis reactions. A cofactor is usually metal ions. Define anabolism. Your Answer: Anabolism is the building up or biosynthesis of smaller molecules into larger, more complex macromolecules. Anabolism is growth and repair Anabolism is the process of building up or biosynthesis of macromolecules from small molecular units into much larger complexes. Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell? Your Answer: Anabolism The anabolic process would be active as it (by definition) is involved in the building up of small complexes into larger complexes. Describe the energy transfer process relative to both ATP and ADP. Your Answer: ATP has the energy to donate a phosphate group to ADP and ADP has the ability to recieve phosphate from ATP. Essentially, ATP is ADP plus Phosphate ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a phosphate group. Thus, ATP can be dephosphorylated (ATP ⟶ ADP + Pi), while ADP can be phosphorylated into ATP (ADP + Pi ⟶ ATP). An organism that derives its energy (generates ATP) from photons of light is called a ? Your Answer: Phototrophic organism Phototrophic microorganism An organism that derives its energy by removing electrons from elemental sulfur would be classified as a ? Your Answer: Lithotroph Lithotroph A reactive intermediate would be present in which phosphorylation process? Photophosphorylation Substrate-level phosphorylation The chemical compound losing the phosphate group is referred to as the phosphorylated reactive intermediate. Oxidative phosphorylation The catabolism of a single molecule of glucose goes through what 3 distinct transitions? Your Answer:
