How many times decarboxylation occurs during each TCA cycle?

Options

  1. AOnce
  2. BTwice
  3. CThrice
  4. DMany

Correct answer

B. Twice

Step-by-step solution

During TCA cycle, first decarboxylation occurs when Oxalosuccinic acid is converted into -ketoglutaric acid and second decarboxylation occurs when -ketoglutaric acid is converted into succinyl CoA.
