How does brown adipose tissue generate heat
WebThe main role of brown adipose tissue is to generate heat through non-shivering thermogenesis; a process that’s especially important to prevent hypothermia in newborns. … WebIt is well known that cells of brown adipose tissue, used for thermogenesis, express uncoupling proteins which dissipate the proton gradient across the inner mitochondrial membrane, generating heat. There are also medications (2,4-dinitrophenol) that do the same thing, leading to higher energy usage but uncontrolled heat production.
