True or False: Metabolism is a controlled set of biochemical reactions that occur in living
organisms to maintain life.
Q: Is metabolism a controlled set of biochemical reactions that occur in living organisms to
maintain life?
A: ✔✔ True
T/F: Enzymes are polysaccharides that catalyze chemical reactions.
Q: Are enzymes polysaccharides that catalyze chemical reactions?
A: ✔✔ False (enzymes are proteins)
What are usually metal ions and assist enzymes during the catalysis reaction?
Q: What are usually metal ions that assist enzymes during catalysis reactions?
A: ✔✔ Cofactors
Define catabolism.
Q: What is catabolism?
A: ✔✔ The process of breaking down larger molecules into useful energy sources.
Upon cellular injury, which metabolic process is involved during the growth and repair
phases of the cell?
Q: Which metabolic process is involved during the growth and repair phases of the cell after
injury?
A: ✔✔ The anabolic process would be active as it is involved in the building up of small
complexes into larger complexes.
, Describe energy transfer process relative to both ATP and ADP.
Q: How does the energy transfer process work between ATP and ADP?
A: ✔✔ 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).
An organism that derives its energy (generates ATP) from photons of light is called what?
Q: What is an organism that generates ATP from photons of light called?
A: ✔✔ Phototrophic microorganism
An organism that derives its energy by removing electrons from elemental sulfur would be
classified as what?
Q: What type of organism derives its energy by removing electrons from elemental sulfur?
A: ✔✔ Lithotroph
A reactive intermediate would be present in which phosphorylation process?
Q: In which phosphorylation process would a reactive intermediate be present?
A: ✔✔ (Answer missing from original document; may need clarification or expert input.)
The chemical compound losing the phosphate group is referred to as what?
Q: What is the chemical compound losing the phosphate group called?
A: ✔✔ Phosphorylated reactive intermediate
The catabolism of a single molecule of glucose goes through what 3 distinct transitions?
Q: What are the three distinct transitions in the catabolism of a single molecule of glucose?
A: ✔✔ Glycolysis, Fermentation or Respiration, then the ETC (electron transport chain).
What is the most energetic transition in the catabolism of glucose?
Q: Which transition in the catabolism of glucose is the most energetic?
A: ✔✔ The electron transport chain yields 34 ATP, while both glycolysis and fermentation (or
respiration) each yield only 2 ATP.
