Question

Which of the following functions would you NOT expect to result from the secretion of glucocorticoids (i.e. cortisol) by the adrenal glands?

A. Stimulate gluconeogenesis.
B. Stimulate lipolysis in adipose tissue.
C. Behave as an immunosuppressive.
D. Stimulate sodium reabsorption by the kidneys.
E. Act as an anti-inflammatory.

Answer 1

Glucocorticoids, such as cortisol, secreted by the adrenal glands have multiple functions including stimulating gluconeogenesis, promoting lipolysis, behaving as an immunosuppressive, stimulating sodium reabsorption by the kidneys, and acting as an anti-inflammatory. So, the correct answer is option a.

Step-by-step explanation:

The secretion of glucocorticoids by the adrenal glands can have several functions, including:

1. Stimulating gluconeogenesis: Glucocorticoids enhance the synthesis of glucose and promote the conversion of non-carbohydrate sources into glucose in the liver.
2. Stimulating lipolysis in adipose tissue: Glucocorticoids promote the release of fatty acids from adipose tissue, which can be used as an energy source.
3. Behaving as an immunosuppressive: Glucocorticoids have anti-inflammatory properties and can suppress the immune system. They are used pharmacologically as immunosuppressants in certain medical conditions.
4. Stimulating sodium reabsorption by the kidneys: Glucocorticoids can enhance the reabsorption of sodium ions in the kidney tubules, which helps regulate blood volume and blood pressure.
5. Acting as an anti-inflammatory: Glucocorticoids, such as cortisol, inhibit the inflammatory response of tissues to injury or stress.

So, the correct answer is option a.
