<prompt> All of the following are intermediates of TCA cycle, except :Malonatealpha -ketoglutarateSuccinateFumarate  <response>: Ans. a Malonate is not an intermediate of TCA cycle Malonate Malate competitive inhibitor of succinate dehydrogenase intermediate in TCA cycle. TCA cycle intermediates are Citrate, Isocitrate, a-ketoglutarate, succinyl-CoA, Succinate, Fumarate, Malate, oxaloacetate. Acetyl-CoA is completely oxidised Oxaloacetate is regenerated.
