Question

Which of the following is/are a mechanism(s) and/or action of growth hormone and insulin like growth factors? Check all that apply.

a. GH makes less glucose available for glycogen synthesis and storage.
b. GH also enhances amino acid transport into cells; and to ensure that protein synthesis outpaces breakdown, it suppresses protein catabolism.
c. To provide energy for growing tissues, GH stimulates adipocytes to catabolize fat and release fatty acids and glycerol into the blood.
d. GH promotes Na+, K+, and Cl- retention by the kidneys, enhances Ca2+ absorption, and makes these electrolytes available to the growing tissues.
e. GH makes it necessary for cells to consume their proteins.

Answer 1

The correct answer could be B C D

Answer 2

Answer:

The mechanisms and/or actions of growth hormone and insulin-like growth factors are:

Therefore, the correct answers are b, c, and d.

Step-by-step explanation:

b. GH also enhances amino acid transport into cells; and to ensure that protein synthesis outpaces breakdown, it suppresses protein catabolism.

c. To provide energy for growing tissues, GH stimulates adipocytes to catabolize fat and release fatty acids and glycerol into the blood.

d. GH promotes Na+, K+, and Cl- retention by the kidneys, enhances Ca2+ absorption, and makes these electrolytes available to the growing tissues.

These are the correct mechanisms and/or actions of growth hormone and insulin-like growth factors.

a. GH does not make less glucose available for glycogen synthesis and storage. In fact, GH can increase blood glucose levels by stimulating gluconeogenesis (the production of glucose from non-carbohydrate sources) in the liver.

e. GH does not make it necessary for cells to consume their proteins. In fact, as mentioned in option b, GH suppresses protein catabolism to ensure that protein synthesis outpaces breakdown.
