Figure 6.19 Regulation of the synthesis of glycogen from glucose in liver and muscle. Insulin is the major factor stimulating glycogen synthesis in muscle it increases glucose transport into the muscle and the activity of glycogen synthase, activity which is also activated by glucose 6-phosphate but inhibited by glycogen. The latter represents a feedback mechanism and the former a feedforward. The mechanism by which glycogen inhibits the activity is not known. The mechanism for the insulin effect is discussed in Chapter 12. Figure 6.19 Regulation of the synthesis of glycogen from glucose in liver and muscle.

As mentioned previously, the endocrine system is concerned with maintaining homeostasis in the body. When a disturbance in physiologic function occurs, hormones are released to rectify the disturbance. As function returns to normal, hormone release is attenuated and homeostasis is resumed. For example, an increase in the blood glucose level initiates the release of insulin from pancreatic beta cells. Insulin increases the incorporation into and storage of glucose in liver, skeletal muscle, and other tissues. Blood glucose levels then return to normal, and insulin release is terminated. [Pg.408]
