The effect on the net reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase if phosphate were replaced by arsenate. Introduction: Arsenate (As) is chemically and structurally similar to inorganic phosphate and many other enzymes that need phosphate will also use arsenate. Organic compounds of arsenate are less stable compared to analogous phosphate compounds. On the other hand 1, 3-bisphosphoglycerate ( acyl phosphates ) is most stable and undergoes enzyme-catalyzed transformation in cells.
