Summary

FREEZING OF BOVINE, CALF, AND PORCINE SKELETAL MUSCLES AT 253 K BEFORE OR AFTER RIGOR MORTIS AND THAWING AT ROOM TEMPERATURE DID NOT CAUSE SIGNIFICANT CHANGES IN THE TOTAL ACTIVITIES OF THE MITOCHONDRIAL ENZYMES. FREEZING (PRE OR POSTRIGOR) AND THAWING RESULT IN A PARTIAL RELEASE OF THESE ENZYMES FROM THEIR BINDING TO THE INNER MEMBRANE OF THE MITOCHONDRIA. IT IS DUE TO DAMAGE OF THE MITOCHONDRIAL MEMBRANES BY FREEZING AND THAWING. DURING LONGER STORAGE AT 2 DEG C THE MITOCHONDRIA BECOME MORE LABILE TOWARDS FREEZING.
