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.
