Question

Quizplus · Accepted Answer

Nonshivering thermogenesis is the generation of heat in response to cold that does not involve muscle shivering. It is stimulated by hormones such as epinephrine and thyroid hormone. This process involves the activation of brown adipose tissue, which generates heat by uncoupling oxidative phosphorylation from ATP synthesis, resulting in the release of energy in the form of heat.
