Final answer:
Indirect calorimetry is a method used to calculate various measurements related to energy expenditure, such as total energy expenditure and resting energy expenditure.Correct option is 1.
Step-by-step explanation:
Indirect calorimetry is a method used to calculate various measurements related to energy expenditure. It can be used to calculate total energy expenditure, resting energy expenditure, and respiratory quotient. However, it does not calculate nitrogen balance or the heat released from the subject.
Indirect calorimetry involves measuring oxygen consumption and carbon dioxide production to estimate energy expenditure. This can be done using methods such as the Benedict-Roth spirometer or by measuring the heat produced by burning food samples in an oxycalorimeter.
Overall, indirect calorimetry is a valuable tool in understanding metabolism and energy expenditure in the human body.
