The basal metabolic rate, or BMR, of a person is defined as what specific quantity?
AThe maximum power a person's muscles can ever produce
BThe energy used only during vigorous exercise
CThe amount of food eaten per day, measured in kilocalories
DThe total energy conversion rate of a person at rest
Answer & Solution
Correct answer: D. The total energy conversion rate of a person at rest
1. The basal metabolic rate is defined as the total energy conversion rate of a person at rest.
2. This rate is divided among various organs and systems in the body, even while the person is not exercising.
3. It is not a measure of maximum muscular power, nor of energy used only during vigorous activity, since it specifically describes the resting state.
4. BMR is a rate of energy conversion, not simply the amount of food eaten, though food intake supplies the energy this rate consumes.
