Energy homeostasis
From Wikipedia, the free encyclopedia
In biology, energy homeostasis, or the homeostatic control of energy balance, is a biological process that involves the coordinated homeostatic regulation of food intake (energy inflow) and energy expenditure (energy outflow).[1][2][3] The human brain, particularly the hypothalamus, plays a central role in regulating energy homeostasis and generating the sense of hunger by integrating a number of biochemical signals that transmit information about energy balance.[2][3][4] Fifty percent of the energy from glucose metabolism is immediately converted to heat.[5]
Energy homeostasis is an important aspect of bioenergetics.
