Maximum assayable hexokinase activities vary with the proportion of red, fast-twitch, oxidative-glycolytic and intermediate, slow-twitch, oxidative fibres in different rat skeletal muscles. The major isoenzymic form, type II hexokinase, is present throughout the intermyofibrillar sarcoplasm in all fibres but a proportion of the total activity appears to be weakly associated with mitochondria. Variations in the histochemical staining intensity between fibre types correlate with their mitochondrial content and seem to be due mainly to differences in mitochondrially-associated hexokinase activity. Changes in the strength of this association may be important in controlling increases in glucose metabolism in response to prolonged increased muscular activity while regulation of the equilibrium between free and loosely-bound forms may be an important control feature in all skeletal muscle. Type I hexokinase is a minor isoenzymic component of skeletal muscle and occurs mainly in blood vessels and nerves in the perimysia and endomysia. The majority of this isoenzyme is tightly bound to mitochondria and is not detectable in homogenates prepared in the absence of Triton X-100.
