Question

Which of the following correctly defines the term "basal metabolic rate"?

1) quantification of calories expended on circulation, nerve transmission, and respiration
2) quantification of calories needed to maintain body weight
3) quantification of calories needed to maintain lean body mass
4) quantification of calories expended on digestion and absorption

Answer 1

The basal metabolic rate (BMR) is the rate at which the body uses food energy to sustain life and perform various activities while at rest. It represents the amount of daily energy expended by humans at rest, in a neutrally temperate environment, and in the postabsorptive state. The correct answer is option 2) quantification of calories needed to maintain body weight.

Step-by-step explanation:

The basal metabolic rate (BMR) is the rate at which the body uses food energy to sustain life and perform various activities while at rest. It represents the amount of daily energy expended by humans at rest, in a neutrally temperate environment, and in the postabsorptive state.

Option 2) quantification of calories needed to maintain body weight is the correct definition of basal metabolic rate (BMR) because it measures the minimum energy required to maintain basic bodily functions, such as heart rate, respiration, and kidney function.
