Question 8

After reading the paragraph below, answer the question(s) that follow(s).
Under normal conditions, blood sugar levels are controlled within a narrow range by negative feedback. Two hormones are involved in maintaining blood sugar levels at the set point (about 90 mg of glucose/100 ml of blood). When blood sugar levels rise above the set point, the hormone insulin signals the liver to absorb the excess sugar. When blood sugar levels drop below the set point, the hormone glucagon signals the liver to release its stored glucose to the bloodstream. In juvenile onset diabetes, the body doesn't produce enough insulin and insulin supplements are required.

-If you hadn't eaten for several hours, the levels of insulin in your blood would be

A) relatively low in response to lower blood glucose.
B) relatively high to try to promote glucose uptake into tissues.
C) about the same as if you had just eaten.
D) relatively high because the rate of its release from the pancreas would be high.
