"QUESTION 15 The hormone insulin enhances the transport of glucose into most of the body's cells: Insulin secretion is controlled by a negative- feedback system between the concentration of glucose in the blood (stimulus) and the cells that secrete insulin (response): Which of the following statements is correct? A decrease in blood glucose concentration will stimulate insulin secretion, which will in turn increase the blood glucose concentration: An increase in blood glucose concentration will stimulate insulin secretion, which will in turn increase the blood glucose concentration still further. A decrease in blood glucose concentration will stimulate insulin secretion; which will in turn lower the blood glucose concentration still further. An increase in blood glucose concentration will stimulate insulin secretion; which will in turn lower the blood glucose concentration."

Step 1
This means that when insulin is present, glucose is taken up by cells and used for energy or stored as glycogen. Insulin secretion is controlled by a negative-feedback system between the concentration of glucose in the blood (stimulus) and the cells that secrete Show more…

Q1) The effects of insulin on glucose uptake by muscle tissue are most directly opposed by A. cortisol. B. glucagon. C. somatomedin A. D. thyroid hormones. Q2) Cyclic AMP A. inhibits glucose-6-phosphatase. B. is degraded in response to high glucagon levels. C. is synthesized directly from AMP. D. modulates the level of fructose 2,6 bisphosphate.

Increased blood glucagon causes blood glucose levels to rise. Which of the following contributes to this? Choose One A.) Fructose 1,6-bisphosphatase is inhibited. B.) Fructose 2,6-bisphosphate levels increase. C.) PFK-2 is inactivated. D.) Glycogen phosphorylase is dephosphorylated. E.) PFK-1 activity is increased. Which of the following statements regarding insulin is FALSE? Choose One A.) Insulin stimulates the liver to store fatty acids as triacylglycerols. B.) Insulin signals the fed state. C.) Insulin works through activating phosphatases. D.) Insulin results in a lowering of the blood glucose levels.
