Question 1) What is the main source of carbon atoms for ketone bodies in a diabetic? A. heart B. liver C. brain D. adipose E. skeletal muscle

Question 2) The insulinreceptor has in common with other growthfactor receptors such as epidermal growth factor A. the ability to phosphorylate tyrosine residues on certain proteins. B. the ability to phosphorylate serine residues on certain proteins. C. their location in the cytosol. D. the ability to bind steroid hormones. E. the presence of a bound GTP.

Question 3) Chemically, the estrogens are characterized by A. the 21 carbon steroid skeleton. B. the lack of a methyl group at C-10. C. the aromatic character of the A ring. D. the lack of a hydroxyl function at C-17. E. all of these.

Solution

Ans 1 D adipose tissue

In diabetes when body switches to oxidation of fatty acids from adipose tissue leading to formation of ketone bodies such as aceto acetate and beta hydroxy butyrate. These decrease the blood ph, a condition called as diabetic ketoacidosis.
