4.2. Skeletal Muscle Intracellular Signaling
muscle contractions
The regulation of muscle glucose utilization consists of three serial steps: the delivery of glucose from the blood to the muscle membrane, the transport across the muscle membrane, and the phosphorylation of glucose-6-phosphate. Upon stimulation by insulin [The translocation of GLUT-4 is caused by muscle contractions caused by the activation of AMPK [The phosphorylation of glucose by hexokinase is required for glucose uptake in skeletal muscle [
