When the pituitary gland releases human growth hormone GH, what is the effect on the liver?
Correct answer: B. Stimulates the liver to convert glycogen to glucose
- A. Stimulates the pituitary gland to release GH
- B. Stimulates the liver to convert glycogen to glucose
- C. Stimulates the liver to store glucose
- D. Decreases sugar level in blood
Explanation
When the pituitary gland releases human growth hormone (GH), it primarily stimulates the liver to convert glycogen to glucose. This process, called glycogenolysis, provides a quick source of energy to meet the body's demands, especially during times of stress or exercise. This increased availability of glucose in the bloodstream helps to maintain blood sugar levels and provide energy for various physiological processes.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
