Question

Quizplus · Accepted Answer

Thermogenin (UCPI) is found in brown adipose tissue, where it creates a passive proton channel through which protons flow from the cytosol to the mitochondrial matrix, generating heat instead of ATP. This process is known as thermogenesis and is important for maintaining body temperature in hibernating animals and newborns. Thermogenin is not found in myelin, nerve, or cardiac tissue.
