Why is succinyl-CoA an appropriate signal for regulation of the citric acid cycle?
O The depletion of succinyl-CoA occurs in response to inhibition of oxidative phosphorylation.
O Succinyl-CoA is the source of activated twocarbon units oxidized by the citric acid cycle.
O By regulating citrate synthase, succinyl-CoA controls entry of acetylCoA into the citric acid cycle.
O Succinyl-CoA is the primary product of the citric acid cycle.
