Quizplus · Accepted Answer

The uncoupling of respiration by the protein thermogenin (found in brown adipose tissue) enables the mitochondria to produce heat instead of ATP, which can raise body temperature. This process is observed in hibernating animals and newborn humans, among others. Shivering and an increase in the rate of glycolysis primarily generate heat in non-hibernating animals. Leakage of hydrogen ions across the plasma membrane and cytochrome reductase are not involved in thermogenesis.
