3.2.4

Explain the role of insulin in the formation of glycogen and the accumulation of body fat.

Insulin and glucagon regulate the sugar level in the body
These two hormones are manufactured in the pancreas and through circulation are carries to the liver where they perform their functions
Enzymes convert glucose to glycogen through a condensation reaction stimulated by insulin
Storage of triglycerides in the adipose tissue is stimulated by insulin.
Receptors in the pancreas are sensitive to the changes in sugar levels, thus releasing the necessary requirements of insulin and glucagon depending on the needs of the body
A diet high in sugar and fat will result in a high release of insulin and consequently an increase in glycogen storage and accumulation of fat

Beta cells release insulin -> cells uptake glucose and send signals to liver and skeletal muscle and convert the glycogen (stops glucogenesis and lipolysis) promotes glycogenesis
