Abstract
LIVER mitochondrial succinoxidase (SO) activity of hibernating hamsters is markedly lower than that of cold-acclimatized awake controls when assayed at the body temperature of the hibernating hamsters, 7° C1,2. However, when the same mitochondrial preparations are assayed at the body-temperature of awake hamsters, 37° C, no such difference is observed1,2. It is apparent that an SO-inhibiting substance or mechanism in the mitochondria of the hibernating animals operates at 7° C. but not at 37° C.
