Explain how insulin and glucagon regulate the balance (i.e, homeostasis) between glycogen and glucose when epinephrine (i.e., adrenalin) is not involved.
Insulin lowers the sugar level, glucagon breaks down glycogen to glucose when needed to increase sugar level.
Insulin is a ligand.
TRUE
Where do fats in the body play a role in balance between glucose and glycogen?
Glucose is the key source of energy for the human body,the liver acts as the bodys glucose,the livers main roles in the body is controlling the amount of glucose circulating in the blood.Our body needs a constant supply of glucose for cells to have energy so it requires a readily available reservoir to keep blood glucose in balance.
