Which 3 enzyme-regulated reactions of glycolysis are replaced by alternative reactions in the gluconeogenic pathway?

Question

Quizplus · Accepted Answer

The three enzyme-regulated reactions of glycolysis that are replaced by alternative reactions in the gluconeogenic pathway are glucokinase, PFK-1, and pyruvate kinase. In the gluconeogenic pathway, glucose-6-phosphatase replaces glucokinase, fructose-1,6-bisphosphatase replaces PFK-1, and phosphoenolpyruvate carboxykinase (PEPCK) replaces pyruvate kinase. These alternative reactions are necessary to bypass the irreversible steps in glycolysis and allow the synthesis of glucose from non-carbohydrate precursors.
