what is metabolic rate?

amount of energy released in body per unit time
amount of nitrogen ingested minus amount of nitrogen excreted
amount of calories consumed per unit time
amount of atp generated per mole of glucose oxid

Explanation:

Metabolic rate is defined as the amount of energy the body uses per unit time. The first option matches this definition.

Answer:

A. Amount of energy released in body per unit time
