Question

which of the following statements about blood glucose is false?
a after a carbohydrate - rich meal, the pancreas secretes insulin, which causes cells to take glucose out of the blo
cellular energy or anabolic reactions, such as glycogenesis and lipogenesis.
b the skeletal system stores excess glucose to help maintain blood glucose.
c when blood glucose drops, the pancreas secretes glucagon, which causes cells to stop using glucose, ar
break down glycogen (thereby releasing stored glucose into the blood).
d none of the above statements is false.

Explanation:

• Option A: After a carbohydrate - rich meal, insulin is secreted, which promotes glucose uptake by cells for energy or storage (glycogenesis), not anabolic reactions like lipogenesis (lipogenesis is more related to fat synthesis from non - carbohydrate sources).
• Option B: The skeletal system does not store excess glucose. The liver and muscles store glucose as glycogen.
• Option C: When blood glucose drops, glucagon is secreted, which causes glycogen breakdown (glycogenolysis) to release glucose into the blood, not to stop cells from using glucose.

Answer:

A. After a carbohydrate - rich meal, the pancreas secretes insulin, which causes cells to take glucose out of the blood for cellular energy or anabolic reactions, such as glycogenesis and lipogenesis.
B. The skeletal system stores excess glucose to help maintain blood glucose.
C. When blood glucose drops, the pancreas secretes glucagon, which causes cells to stop using glucose, and break down glycogen (thereby releasing stored glucose into the blood).
