Which of the following statements best describes an aspect of the normal process of glucose metabolism?
A)
Blood glucose levels are primarily a result of the timing, quantity, and character of food intake.
B)
Ingested glucose that is not needed for cellular metabolism circulates in the blood until it is taken up to meet cellular needs.
C)
Blood glucose levels are kept in a steady state by selective excretion and reuptake by the kidneys.
D)
Glucose that exceeds metabolic needs is converted and stored by the liver.
Ans:
D
Feedback:
Approximately two thirds of the glucose that is ingested with a meal is removed from the blood and stored in the liver as glycogen. Between meals, the liver releases glucose as a means of maintaining blood glucose within its normal range. Normal glucose metabolism does not involve large variations in blood glucose levels in response to food intake, and excess glucose does not normally remain in circulation. Glucose levels are not primarily maintained by the kidneys.
