Question

In citric acid cycle, decarboxylarion occurs when (A) citric acid converts to α -ketoglutaric acid (B) succinic acid converts to malic acid (C) malic acid converts to oxaloacetic acid (D) oxaloacetic acid converts to citric acid

Tardigrade Admin · Accepted Answer

In citric acid cycle, decarboxylation is the first step, where a carbon group is lost as carbon dioxide in a decarboxylation reaction. The remaining compound now has 5 carbons and is called alpha-ketoglutaric acid. This reaction is also catalysed by isocitrate dehydrogenase.

Q. In citric acid cycle, decarboxylarion occurs when

citric acid converts to $α$ -ketoglutaric acid

succinic acid converts to malic acid

malic acid converts to oxaloacetic acid

oxaloacetic acid converts to citric acid
