three parameters of structural and functional significance in freshly isolated rat-liver mitochondria have been correlated with the structural alterations observed : ( a ) chemical composition ( total protein , lipid phosphate and total phosphate ) , ( b ) specific and total activities of marker enzymes for mitochondrial matrix and membranes ( malate dehydrogenase ( mdh ) , d-beta-hydroxybutyrate dehydrogenase ( bdh ) and cytochromes ) , and ( c ) integrated multienzyme functions ( respiration , phosphorylation , and contraction ) .
