The enzyme decarboxylase catalyses the following step

Options

A. conversion of citric acid to cis aconitic acid
B. fumaric and to malic acid
C. oxalosuccinic acid to `alpha-` ketoglutaric acid
D. malic acid to oxaloacetic acid

Answer

C

Explanation

Oxalosuccinate is decarboxylated to form `alpha`-ketoglutarate through the enzyme decarboxylase. It is one of the step involved in Krebs' cycle. It releases one molecule of `CO_(2)`.
`"Oxalosuccinate"overset("Decarboxylase")underset(Mg^(2+))rarr alpha-"ketoglutarate"+CO_(2)`
