Insulin and Glucagon are two hormones produced by the pancreas whose primary function is to regulate the carbohydrate metabolism.
GlucagonIt is a polypeptide hormone.
It is secreted by the pancreas when the glucose level in the blood drops.
It increases the blood glucose levels by initiating glycogenolysis (glycogen degradation) and stimulating gluconeogenesis (synthesis of glucose from non-carbohydrate molecules) in the liver cells.
Since it increases the blood glucose levels it is a hyperglycemic (hyper-more, glycemic-sugar levels) hormone
It also initiates lipolysis (degradation of lipid) in the adipose tissue.
Insulin
It is also a polypeptide hormone
It has antagonistic (opposite) effects of the hormone glucagon.
It is released when the glucose level in the blood raises.
It lowers blood sugar levels in different ways; increasing the uptake of glucose by all the cells in the body, initiating glycogenesis (glycogen synthesis) in the liver and muscle.
It initiates lipogenesis (synthesis of lipids/fat) and storage of fat in adipose tissue and inhibits gluconeogenesis
It is a hypoglycemic (hypo=less) hormone as it reduces the sugar levels in the

Blood calcium levels are maintained because the bones act as a calcium sink in which calcium can either be stored or procured based on the body's needs. If a person secretes too much parathyroid hormone (one possible factor in the bone disease osteoporosis), what happens to calcium levels in the body?Question 4
The given figure shows feedback relationship between three glands and their hormones. The secretion of ?b? is decreased by 'a', secretion of 'c' is increased by 'b' while the secretion of 'a' is decreased by 'c'. Increased or decreased amounts of a hormone cause an increase or decrease in the amount of the following hormone in the system. Now if 'a' is added to the system, the secretion of 'c' isStuck on the question or explanation?
