Standard metabolic rate (SMR) and basal metabolic rate (BMR) are ________.
A) used differently: SMR is measured during exercise, whereas BMR is measured at rest
B) used to compare metabolic rates during feeding and other active conditions
C) both measured across a wide range of temperatures for a given species
D) both measured in animals in a resting and fasting state

Question

Quizplus · Accepted Answer

Both SMR and BMR are measured in animals in a resting and fasting state. SMR is measured during low-level activity, while BMR is measured at complete rest. They are both used to compare different species' metabolic rates, but they are not measured during feeding or other active conditions. Although they can vary with temperature, they are typically measured at a standard temperature for each species.
