Question

The hormone which regulates the amount of glucose in the blood by converting excess of glucose into glycogen is (1)_______. The hormone which regulates glucose in the blood by converting glycogen back to glucose whenever required is (2)_______.

• A. Insulin and Glucagon
• B. Glucagon and Insulin.
• C. Insulin and Somatostatin
• D. Glucagon and Somatostatin

Answer 1

The correct option is A

Insulin and Glucagon

1. Insulin is a hormone produced by beta-cells of islets of Langerhans. It regulates the amount of glucose in the blood by converting excess of glucose into glycogen which can be stored in the liver and muscles.

2. Glucagon is a hormone produced by alpha-cells of islets of Langerhans. It also regulates the amount of glucose in the blood by converting glycogen back to glucose whenever required. Thus, its effect is opposite to that of insulin.
