which of the following enzyme is called regulatory of glycolysis

1. phosphoglucoisomerase
2. phosphofructokinase
3. phosphotriose isomerase
4. mutase

Hello Student
Correct answer is 2. Phosphofructokinase
Phosphofructokinase called regulatory enzyme of glycolysis. It is inhibited by high concentration of ATP and is stimulated by ADP and Pi.

The correct answer is (2) Phosphofructokinase

In glycolysis, the reactions catalyzed by hexokinase, phosphofructokinase, and pyruvate kinase are virtually irreversible; hence, these enzymes would be expected to have regulatory as well as catalytic roles.
