All of the following statements concerning gluconeogenesis are correct EXCEPT which one?
A) gluconeogenesis from lactate occurs in both mammalian liver and muscle.
B) One mole of glucose is produced from two moles of lactate.
C) Given ATP, all the reactions of gluconeogenesis can occur in the absence of air.
D) Although a net of two molecules of ATP are generated per molecule of glucose converted to lactate, six molecules of ATP (or its equivalent) are required to synthesize one molecule of glucose from lactate.
E) Photosynthesis in green plants utilizes part of the gluconeogenic pathway for hexose synthesis.

Question

Quizplus · Accepted Answer

Gluconeogenesis from lactate primarily occurs in the liver and to a lesser extent in the kidneys, but not in muscle. Muscle lacks the necessary enzymes to convert lactate back into glucose, which is a key step in gluconeogenesis.
