BIO 100 EXAM 2 ACTUAL QUESTIONS AND
CORRECT ANSWERS
◉ enzymes.
Answer: proteins that catalyze (speed up) and regulate metabolic
reactions
◉ metabolic rate.
Answer: the measure of a person's energy use
◉ Metabolic rate is influenced by many factors:.
Answer: exercise, biological sex, genetics
◉ basal metabolic rate (BMR).
Answer: the energy use of a resting, wakeful person
◉ Average BMR is.
Answer: 70 calories/hour or 1680 calories/day
◉ cellular respiration.
Answer: series of metabolic reactions converting food energy into
usable form
,◉ uses of ATP.
Answer: - movement of cells

- making complex molecules
◉ adenosine triphosphate (ATP).
Answer: - consists of adenine, a ribose sugar, and 3 phosphate
groups
- energy stored in chemical bonds of ATP
◉ phosphorylation.
Answer: phosphate group is transferred to another molecule
- energy is transferred
- ADP is produced
