➢ Expert-Verified Explanations
,1. True or False: Enzymes slow down chemical reactions to conserve
energy.
Answer choices: True / False
Correct Answer: False
Expert Rationale: Enzymes function as biological catalysts that accelerate
(catalyze) chemical reactions by lowering the activation energy, enabling
reactions to proceed rapidly under physiological conditions. Slowing
reactions would be energetically disadvantageous.
---
2. True or False: As movement requires energy, metabolism can be
defined as a controlled set of biochemical reactions that occur only in
motile organisms in order to maintain life.
Answer choices: True / False
Correct Answer: False
Expert Rationale: Metabolism is universal and occurs in all living
organisms regardless of motility. Non-motile organisms, such as plants and
many bacteria, undergo metabolism to maintain vital functions including
growth and repair, independent of movement.
---
, 3. True or False: Metabolism is a controlled set of biochemical
reactions that occur in living organisms in order to maintain life.
Answer choices: True / False
Correct Answer: True
Expert Rationale: Metabolism encompasses all enzymatic reactions that
allow cells to extract energy from nutrients, synthesize cellular components,
and regulate homeostasis. It coordinates catabolic and anabolic pathways
essential for sustaining life. This complex regulation is critical for survival,
growth, and reproduction of all living organisms.
4. True or False: Enzymes are polysaccharides that catalyze chemical
reactions.
Answer choices: True / False
Correct Answer: False
Expert Rationale: Enzymes are primarily proteins (though some RNA
molecules called ribozymes also have catalytic function). They are
composed of amino acid polymers with tertiary and quaternary structures
that allow substrate specificity and catalysis, unlike polysaccharides which
are structural or storage carbohydrates.

5. What is a cofactor? Give a general example.
