Question

Which measurement may be used to calculate the amount of energy expended by the body? ​

Quizplus · Accepted Answer

The measurement of oxygen consumed can be used to calculate the amount of energy expended by the body through the process of respiration, as energy is released when oxygen is used to metabolize nutrients. Total air exchanged and intestinal gas expelled do not directly relate to energy expenditure, and while carbon dioxide production is also a byproduct of metabolism, it is not as accurate a measurement as oxygen consumption.
