Changes in heart and skeletal muscle cytrochrome oxidase activity during anaerobiosis in the freshwater tutrle Pseudemys scripta elegans
1.
1. Changes in cytochrome oxidase activities following prolonged oxygen depletion induced by a maintained underwater “drive” were investigated in the pond turtle (Pseudemys scripta elegans).
2.
2. A marked decrease in both heart and skeletal muscle cytochrome oxidase activity was seen following 48 hr of total anaerobiosis. Heart: Control = 4·05 ± 0·86; diving = 3·07 ± 0·74; P = < 0·05. Skeletal muscle: Control = 0·90 ± 0·24; diving = 0·44 ± 0·13; P < 0·01.
3.
3. This decrease may be a consequence of a need for molecualr oxygen in porphyrin biosynthesis, may subserve increased metabolic efficiency, or may be a reflection of the lowered (zero) mitochondrial oxgyen consumption.
