1. 1. In the present work the initially lowered oxidase activity of liver mitochondria of hibernating gophers is shown to increase upon Ca2+-loading, after freezing-thawing repeated three times and after swelling in a medium containing potassium acetate as well as in a hypotonic sucrose medium. 2. 2. In all cases the inhibition of phospholipase A2 hindered the increase of the oxidase activity of mitochondria. 3. 3. Mitochondria of hibernating gophers have a lowered Δψ in comparison with active animals, which is restored in the hypotonic medium.
