Describe how insulin affects the metabolism of carbohydrate

– it increases the rate of uptake of glucose by muscle and fat cells through a number of glucose channels in the cell surface membrane.

– Insulin increases the utilization of glucose by the cells in the process of respiration.

Insulin increases the rate at which glucose is converted to glycogen in the liver and muscle cells (glycogenesis).

Insulin inhibits the formation of glucose from non-carbohydrates sources in the liver (gluconeogenesis) and also inhibits the process of glycolysis.
