The substrate in Krebs cycle which undergoes a reaction very similar to pyruvic acid in mitochondria is

Options

  1. Aaconitate
  2. Bsuccinic acid
  3. Calpha-ketoglutaric acid
  4. Dfumaric acid

Correct answer

C. alpha-ketoglutaric acid

Step-by-step solution

In the mitochondria, pyruvic acid undergoes oxidative decarboxylation to form acetyl Co-A as follows: In Krebs cycle, alpha-ketoglutaric acid also undergoes oxidative decarboxylation to form succinyl co-A as follows:
