Question

What effect does insulin have in a normal human body?

• A. It mediates release of glucose by the liver cells
• B. It stimulates formation of glycogen in the liver
• C. It stimulates conversion of glycogen into glucose
• D. it increase absorption of glucose in the small intestine

Answer 1

The correct option is B

It stimulates formation of glycogen in the liver

The correct option is (B).

Explanation of correct option:

1. Insulin produced within the liver is known to stimulate the accumulation of glycogen in the liver.
2. It does so to control the blood sugar level when it rises. It converts the excess glucose in the blood and thus keeps the blood sugar level in check.

Explanation of incorrect options:

Option (A):

1. The release of glucose from the liver is when there is a need for energy and not enough glucose is taken up.
2. So glycogen stored in the liver is broken down and glucose is released for energy production.

Option (C):

The glycogen to glucose conversion is promoted by the hormone known as glucagon.

Option (D):

The absorption of glucose happens via the microvilli in the small intestine walls and due to the large surface area of the villi the glucose is absorbed faster into the blood.

Final answer:

Insulin stimulates the formation of glycogen in the liver
