WebEnzymes are regulated by those membranes. For example, lysosomes are membrane-bound organelles that assist in breaking down cellular material. Enzymes inside … WebYou might wonder why pyruvate kinase, the last enzyme in the pathway, is regulated. The answer is simple. Pyruvate kinase catalyzes the most energetically rich reaction of glycolysis. The reaction is favored so strongly in the forward direction that cells must do a ‘two-step’ around it in the reverse direction when making glucose.
