Answer to Question 1

Ans:
A, C, D

Feedback:

A number of disease conditions and pharmacologic agents can decrease the amount of binding protein in the plasma or influence the binding of hormone. Glucocorticoid medications and systemic disease conditions such as protein malnutrition, nephritic syndrome, and cirrhosis decrease TBG concentrations.

Answer to Question 2

Ans:
D

Feedback:

The presence of fat in the duodenum and nutrients in the small bowel results in the release of cholecystokinin and glucagon-like peptide-1, respectively, which suppress the feeding center located in the hypothalamus. Leptin and ketoacids are associated with the intermediate and long-term regulation of food intake rather than the short-term control that would signal the end of a meal or snack.
