Thermogenesis non-shivering

To produce heat so as to maintain body temperature (known as non-shivering thermogenesis) (Chapter 9). 

The result of uncoupling electron transport from the phosphorylation of ADP is that a great deal of substrate is oxidized, with little production of ATP, although heat is produced. This is one of the physiological mechanisms for heat production to maintain body temperature without performing physical work — non-shivering thermogenesis. There are a number of proteins in the mitochondria of various tissues that act as proton transporters across the crista membrane when they are activated.
