Which of the following hormones is produced under the condition of stress which stimulates glycogenolysis in the liver of human beings?

Adrenaline

The correct answer is (3) Adrenaline.

The hormone that is produced under the condition of stress and stimulates glycogenolysis in the liver of human beings is adrenaline.

Adrenaline, also known as epinephrine, is a hormone that is released by the adrenal glands in response to stress. It is part of the fight-or-flight response, which is a physiological response that prepares the body for danger.

When adrenaline is released, it causes the liver to break down glycogen into glucose. This glucose is then released into the bloodstream, where it can be used by the muscles and other tissues for energy.

The other options are incorrect:

• Thyroxin is a hormone that is produced by the thyroid gland and regulates metabolism.
• Estradiol is a female sex hormone that is produced by the ovaries.
• Insulin is a hormone that is produced by the pancreas and regulates blood sugar levels.
