Abstract:
Glucose-6-phosphatase (G6Pase) activity in the skeletal muscle cells was observed with electron microscope in rats.It was found that the reaction product of G6Pase activity was localized in the sarcoplasmic reticulum (SR) and nuclear envelope and a heterogenous distribution of G6Pase activity in the SR was shown.On the basis of the position relationship between SR and sarcolemmal system,the skeletal couplings can be classified as follows.1.The coupling between the terminal cisternae and the transverse tubules such as a triad.2.The peripheral coupling between the peripheral SR and the surface sarcolemma.3.The coupling between the subsarcolemmal SR and the subsarcolemmaltransverse tubules.The significance of the findings was discussed.
