Question 13

competitive inhibitor of catecholamine synthesis

Answer 13

Metyrosine

Question 14

Where are mineralocotricoids produced in the adrenal gland?

Answer 14

zona glomerulosa of the adrenal cortex

Question 15

Where are androgens produced in the adrenal gland?

Answer 15

zona reticularis of the adrenal cortex

Question 16

Answer 16

dexamethasone > fludrocortisone > triamcinolone > prednisone > cortisol > aldosterone

Answer 17

ketoconazole and aminoglutethimide

Question 18

What is the rate limiting step of cholesterol hormone synthesis?

Answer 18

20, 22 desmolase (conversion of cholesterol to pregnenolone)

Question 19

DHEA is part of what adrenal corticosteroid class?

Answer 19

Androgen

Question 20

Do mineralocorticoids increase or decrease reabsorption of potassium and hydrogen at the kidney?

Answer 20

decrease

Question 21

Do glucocorticoids increase or decrease protein synthesis?

Answer 21

decrease

Question 22

Do glucocorticoids increase or decrease lipolysis?

Answer 22

increase

Question 23

Arrange these adrenocorticosteroids from the most potent to the least potent salt-retaining agent:
Cortisol, prednisone, triamcinolone, dexamethasone, aldosterone, fludrocortisone

Answer 23

aldosterone > fludrocortisone > cortisol > prednisone > triamcinolone = dexamethasone

Question 24

Where are glucocorticoids produced in the adrenal gland?

Answer 24

zona fasiculata of the adrenal cortex

Answer 25

fludrocortisone (maybe DHEA)

Question 26

Do mineralocorticoids increase or decrease reabsorption of sodium at the kidney?

Answer 26

increase
