Answer to Question 1

Ans:
D

Feedback:

GH excess is associated with tumor formation and consequent compression of cranial nerves responsible for vision. Damage to the hypothalamus and liver is not common sequelae. While the beta cells of the pancreas can burn out, the primary effect of excess GH is to increase insulin secretion.

Answer to Question 2

Ans:
C

Feedback:

Steroid hormones are bound to protein carriers for transport and are inactive in the bound state. Their activity depends on the availability of transport carriers.
