Explanation:
Detailed explanation-1: -The TCA cycle begins when acetyl-CoA combines with a four-carbon oxaloacetate in order to form the six-carbon citrate. Because each molecule of glucose produces 2 pyruvate molecules, it takes two turns through the Krebs cycle to completely break down the original glucose.
Detailed explanation-2: -The citric acid cycle begins by acetyl-CoA (2 carbons) combining with oxaloacetate (4 carbons) to form citrate (aka citric acid, 6 carbons).
