Question

Metabolism is an inter-play between two hormones: insulin and glucagon /epinephrine.

Describe how insulin is involved in regulating the metabolism of carbohydrates, fats, and proteins after a well-balanced meal has been eaten. Which metabolic pathways are involved?

Answer 1

Answer =

• Insulin is involved in regulating the metabolism of carbohydrates, fats, and proteins after a balanced meal has been eaten as follows:
• by promoting the absorption of glucose from the blood into liver ,fat and skeletal muscle cells.
• In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats via lipogenesis
• it lowers the blood glucose by increasing glucose transport in muscle and adipose tissues and stimulates the synthesis of glycogen,fat and protein.
• metabolic pathways that are involved are =
• it promotes the Glycogenesis
• lipogenesis
• Insulin promotes the synthesis of fatty acids in the liver
