The 5-C compound formed during TCA cycle is :

The 5-C compound formed during TCA cycle is :
  1. $\alpha$-ketoglutaric acid
  2. Oxalo succinic acid
  3. Succinic acid
  4. Fumaric acid

Solution

During TCA cycle, after first decarboxylation of oxalosuccinic acid, $\alpha$-Ketoglutaric acid 5-C compound ( $\alpha$-KGA) is formed. $\alpha$-KGA undergoes further decarboxylation to form a 4 carbon compound i.e., succinyl-CO-A.
