The Krebs cycle (TCA cycle) begins with the condensation of
AGlucose with ATP making glucose-6-P
BAcetyl CoA with oxaloacetate making citrate
CAcetyl CoA with pyruvate making lactate
DPyruvate with NAD+ making acetyl CoA
Answer & Solution
Correct answer: B. Acetyl CoA with oxaloacetate making citrate
Citrate synthase condenses acetyl CoA with oxaloacetate (OAA) and water to form citrate. CoA is released.
The cycle continues through isocitrate, alpha-ketoglutarate, succinyl CoA, succinate, fumarate, malate, back to OAA.
