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]. Citrate is a positive allosteric activator. High [NADH/NAD*] ratio. NADH is a positive allosteric activator. High [ATP/ADP] ratio. High ATP substrate levels favor product formation.

In the presence of saturating amounts of oxaloacetate, the activity of citrate synthase from pig heart tissue shows a sigmoid dependence on the concentration of acetyl‑CoA. When succinyl‑CoA is added, the curve shifts to the right and the sigmoid dependence is more pronounced.
