BIOD 171 M2: Module 2 Exam True or False: Metabolism is a controlled set of biochemical reactions that occur in living organisms in order to maintain life. True False True or False: Enzymes are polysaccharides that catalyze chemical reactions. True False Enzymes are proteins that catalyze chemical reactions. What is a cofactor? And give a general example. Your Answer: Metal ions are cofactors. Cofactors assist enzymes in the catalysis of reactions. 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 of macromolecules from smaller molecular units into more complex molecules. 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 and ADP is able to accept a phosphate group. ATP is being reduced and ADP is being made into ATP. 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). From what source do chemotrophs acquire energy? Your Answer: Chemotrophs acquire energy from preformed chemicals in the environment. Chemotrophs acquire energy from preformed chemicals found in the environment. An organism that obtains its source of carbon from inorganic molecules such as carbon dioxide is referred to as a ? Your Answer: autotroph Autotroph
