What is the product of the condensation of the acetyl group with oxaloacetic acid and water?

Options

  1. AGlucose
  2. BCitric acid
  3. CPyruvic acid
  4. DLactic acid

Correct answer

B. Citric acid

Step-by-step solution

The TCA cycle starts with the condensation of acetyl group with oxaloacetic acid (OAA) and water to yield citric acid (Figure 12.3). The reaction is catalyzed by the enzyme citrate synthase and a molecule of CoA is released. Citrate is then isomerized to isocitrate.
