The role of Arsenate compound instead of phosphate in glycolysis causes a toxic effect for the cell. Concept introduction: The arsenate ion ( AsO 4 3- ) chemically resembles with phosphate in many respects. It is also used as an alternative substrate by many phosphate-requiring enzymes. In water, an anhydride bond between arsenate and carbon is quickly hydrolyzed non-enzymatically. In glycolysis, the energetically unfavorable reaction is driven by a pair of coupled reaction for the formation of ATP in step 6 and step 7 as energy generation phase.
