Abstract

1. 1. Respiratory rates of wasged and unwashed liver mitochondria from torpid and aroused bats as well as control and cold-acclimated rats were measured at five incubation temperatures. 2. 2. The effects of washing suggest the influence of at least three extramitochondrial factors on succinate oxidation. 3. 3. Although species differences occur at the higher incubation temperatures (37, 29°C), the data do not indicate any differential effects of cold exposure on the metabolic capacity of the mitochondria per se. Rather, the differences observed seem to reflect the influence of extramitochondrial substance which themselves may have been by the animal's trophic response to cold.
