Detailed explanation-1: -In the process of ATP production by cells throughout the body, approximately 60 percent of the energy produced is in the form of heat used to maintain body temperature. Thermoregulation is an example of negative feedback.
Detailed explanation-2: -Body temperature is tightly regulated by a process called thermoregulation, controlled by a master regulator, the hypothalamus that modulates the heat gain or loss by the body. Up to 60% of the heat generated during metabolic processes is used to maintain body temperature.
Detailed explanation-3: -About 60% of all the energy generated by the body, is in the form of heat, in order to maintain the body’s core temperature steady around 36.5–37.5 °C [ 97.7–99.5 °F].
Detailed explanation-4: -Body temperature must be controlled within a very narrow range so that the body can function properly. In particular, enzymes in a body’s cells must have the correct temperature to be able to catalyse chemical reactions.
Detailed explanation-5: -Body temperature is regulated mainly by the hypothalamus in the brain.
