The 5-C compound formed during TCA cycle is :

Options

A-ketoglutaric acid
BOxalo succinic acid
CSuccinic acid
DFumaric acid

Correct answer

A. -ketoglutaric acid

Step-by-step solution

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