1.	The TCA cycle starts with the condensation of which of the following compounds?(a) Sucrose(b) Acetyl group(c) Ethanol(d) PyruvateI had been asked this question in an interview for job.This question is from Aerobic Respiration in section Respiration in Plants of Biology – Class 11
Answer» The correct answer is (B) Acetyl group The explanation is: The TCA cycle starts with the condensation of acetyl group. It reacts with oxaloacetic acid and WATER and forms citric acid. This REACTION is catalysed by the enzyme citrate synthase and a molecule of CoA is released. Further, citrate is isomerised to isocitrate with the help of ISOMERASE enzyme.
