Citrate synthase is regulated by another metabolite that has the opposite effect (i.e., stimulates citrate synthase). Choose the description of a condition where a positive regulator activates citrate synthase. Low [ATP/ADP] ratio. ADP is an allosteric activator of citrate synthase. High [citrate].
