Chemistry

What is the physiological function of gluconeogenesis?

A. Gluconeogenesis is production of glucose from noncarbohydrate molecules in times when blood glucose levels are low. This ensures proper function of brain and red blood cells, which only use glucose as fuel.

B. Gluconeogenesis is production of glucose from noncarbohydrate molecules in times when blood glucose levels are high. This ensures proper function of brain and white blood cells, which only use glucose as fuel.

C. Gluconeogenesis is production of glucose from carbohydrate molecules in times when blood glucose levels are low. This ensures proper function of brain and red blood cells, which only use glucose as fuel.

D. None of the above
