The primary problem in type 2 diabetes is: A)decreased release of glucagon from pancreatic alpha cells. B)increased release of glucagon from pancreatic alpha cells. C)decreased sensitivity of peripheral tissues to circulating insulin. D)increased sensitivity of peripheral tissues to circulating insulin. E)decreased production of antidiuretic hormone.

Certain forms of biosynthetic insulin are absorbed more rapidly than regular human insulin because: A)other substances such as acetate or protamine have been added to the insulin molecule to increase absorption. B)zinc has been added to the insulin molecule to increase absorption. C)newer forms of biosynthetic insulin can be administered orally via slow-release or sustained-release preparations. D)the amino acid sequence of the insulin molecule has been altered to allow more rapid absorption E)none of the above

At the present,insulin must be administered by parenteral (nonoral)routes because: A)insulin will irritate the stomach. B)insulin will be destroyed during "first-pass" metabolism in the liver.
