Some Hibernating animals don't eat during hibernation and come out of hibernation with much less fat than when they started. They hibernate in winter when it's cold and they need to keep their bodies warm. One way to accomplish this is that would also explain the weight loss is ... A) the animal has evolved a way to recapture a lot of the body heat that it loses to the environment Mock Exam 2 - Winter 2020 University of California, Davis: Facciotti MT. ©2020 B) the animal have evolved ways of capturing sunlight to generate heat C) the animal convert their stored fat molecules into ATP molecules; since ATP is highly unstable its uncoupled hydrolysis generates internal heat D) they have evolved proteins that create free proton flow across the inner mitochondrial membrane to generate heats E) they evolved ways to fully oxidize sugars in one big step rather than many small redox steps

C) the animal convert their stored fat molecules into ATP molecules; since ATP is highly unstable its uncoupled hydrolysis generates internal heat .

Hibernation can be referred as winter sleep. It is a process followed by animals to escape cold temperatures during winter. Most of the hibernating animals store fat in their body and have greater body mass. During this hibernation period their body breaks down the stored fat to release heat and keep the animal warm.
