The correct statement about the citric acid cycle is "the last reaction in the citric acid cycle produces a product that is a substrate for the first reaction of the citric acid cycle"

CITRIC ACID CYCLE:

  • Citric acid cycle or Krebs cycle is the second stage of aerobic cellular respiration. It involves a series of enzymatic and redox chemical reactions.

  • The citric acid cycle is composed of eight steps starting from the combination of 2-carbon acetyl coA and 4-carbon oxaloacetate.

  • The last reaction of the citric acid cycle involves the conversion of malate into oxaloacetate, which is one of the substrates for the first reaction.

  • Therefore, the correct statement about the citric acid cycle is "the last reaction in the citric acid cycle produces a product that is a substrate for the first reaction of the citric acid cycle"
