Question

Assertion [A]: Glucagon is said to lower the blood sugar level.

Reason [R]: Glucagon increases the utilization of glucose in the tissues and glycogen in liver.

• A. Assertion [A] is True and Reason [R] is False.
• B. Reason [R] is True and Assertion [A] is False.
• C. Assertion [A] is True and Reason [R] is True and is a correct explanation to [A].
• D. Assertion [A] is True and Reason [R] is True but is the incorrect explanation to [A].

Answer 1

The correct option is D

Assertion [A] is True and Reason [R] is True but is the incorrect explanation to [A].

Glucagon increases blood sugar level and insulin reduces it. They are antagonistic pancreatic hormones. Glucagon stimulates glycogenolysis, thus forming glucose from the breakdown of glycogen. Insulin is the hormone responsible for the entrance of glucose from blood into cells. When glucose level is low, for example, during fasting, glucagon is secreted and insulin is inhibited. When glucose level is high, like after meals, glucagon is inhibited and insulin secretion is increased.
