C. The brain and testis are the most important tissues involved.
D. No high energy phosphate compounds are involved.

Explanation / Answer
Answer:
A. The enzymes that catalyze the 3 irreversible steps of glycolysis are used in the process of glucose synthesis.
Explanation
Gluconeogenesis occurs mainly in liver, rarely in kidneys and small intestine under some conditions.
Synthesis of glucose from pyruvate utilizes many of the same enzymes as Glycolysis. Three reactions of Glycolysis have such a large negative DG in the forward direction that they are essentially irreversible.
