Most bats are inactive during the day (this is known as torpor) and feed during the night. The graph below shows hypothetical data for a bat species.

-Bats contain brown fat between their shoulder blades. How could this brown fat be an adaptation to torpor?

Quizplus · Accepted Answer

Brown fat is an adaptation to torpor because it contains mitochondria that can produce heat without producing ATP. This allows the bat to maintain a higher body temperature during torpor without using up energy reserves needed for activity. Option A is incorrect because brown fat does not produce more ATP than other types of fat. Option B is incorrect because fermentation does not occur in brown fat. Option D is incorrect because white fat is not involved in thermogenesis.
