Question

Decarboxylation occurs during

• A. Glycolysis.
• B. ETS.
• C. Krebs cycle.
• D. All the above.

Answer 1

The correct option is C Krebs cycle.

In Krebs Cycle six carbon compounds like Citric acid converts into Oxalo succinic acid which is five carbon compound and it forms Malic acid which further reacts and forms Oxaloacetic acid which is both four carbon compound. Therefore in each stem carbon is released in the form of carbon dioxide and the process is known as decarboxylation.

So the correct option is 'Krebs cycle.'.
