Textbook Question
Chapter 26, Problem 9TYK
A strain of mice remains healthy as long as they are fed regularly. After they eat, their blood glucose level rises slightly and then declines to a homeostatic level. However, when these mice fast or exercise, their blood glucose drops dangerously. Which hypothesis best explains their problem? (Explain your choice.)
a. The mice have insulin-dependent diabetes.
b. The mice lack insulin receptors on their cells.
c. The mice lack glucagon receptors on their cells.
d. The mice cannot synthesize glycogen from glucose.

- Which of the following statements is true about diabetes? a. It can only be inherited. b. Very few people in the world get the condition. c. It is a result of a mismatch between our evolved bodies and our modern lifestyle. d. Once a person is diagnosed with diabetes, the condition rarely progresses.arrow_forwardndicate whether each of the following statements is true or false. If false, correct the statement or provide a briefexplanation for why it is false.a. Insulin increases the rate of glucose uptake by the tissues.b. Glucagon is the hormone that signals low blood glucose levels.c. The muscles can use glucose, fatty acids and ketone bodies for fuel.d. Epinephrine stimulates breakdown of glycogen in muscles when there is an immediate needfor energy by muscle cells.e. Glucagon stimulates glycogenolysis to maintain the blood glucose concentration.f. With high [carbohydrate] levels, excess glucose (after glycogen storage has reached amaximum) is converted to fat.g. The high potential electrons of NADH enter the respiratory chain at NADH-Q reductase.h. Ubiquinol (QH2) is also the entry point for electrons from NADH of flavoproteins.i.
