1.	Which of the following compounds is the first member of the TCA cycle?(a) Oxaloacetic acid(b) α-ketoglutaric acid(c) Succinic acid(d) Malic acidThe question was asked during an interview for a job.My doubt stems from Aerobic Respiration in chapter Respiration in Plants of Biology – Class 11
Answer» The correct ANSWER is (a) Oxaloacetic acid For EXPLANATION I would say: Oxaloacetic acid is the FIRST member of the TCA cycle. The continued oxidation of ACETYL CoA via the TCA cycle REQUIRES the continued replenishment of Oxaloacetic acid.
