Insulin glycogen synthesis

Nettet10. apr. 2024 · Insulin is produced by beta cells in the pancreas and acts to oppose the functions of glucagon. Its main role is to promote the conversion of circulating glucose into glycogen via glycogenesis in the liver and muscle cells. Insulin also inhibits gluconeogenesis and promotes the storage of glucose in fat through lipid synthesis … NettetInsulin synthesis and secretion occurs in pancreatic islet cells. Insulin has many sites of action, including the liver, where it inhibits gluconeogenesis, skeletal muscle, where it …
