1. Subsarcolemmal and interfibrillar mitochondria were isolated from the hearts of the diving muskrat and non-diving guinea pig and rat. Respiration rates, respiratory control ratio (RCR) and phosphorous to oxygen (P:O) ratios determined. 2. There was no significant difference in these values among the three species or between mitochondrial populations. 3. Mitochondrial yield as measured by citrate synthase of whole heart homogenates was greatest in the rat, intermediate in the muskrat and… CONTINUE READING
