Question

In which one of the following reactions, oxidative decarboxylation does not occur?

• A. Malic acid $ \rightarrow $ Pyruvic acid
• B. Pyruvic acid $ \rightarrow $ Acetyl Co-A
• C. Glyceraldehyde 3-phosphate $ \rightarrow $ 1, 3-bisphosphoglyceric acid
• D. $\alpha $ -ketoglutaric acid $ \rightarrow $ Succinyl Co-A

Answer 1

Answer: (C)

Oxidative decarboxylation reactions are oxidation reactions in which a carboxylate group is removed, forming carbon dioxide. In this reaction, Glyceraldehyde 3-phosphate → 1, 3-bisphosphoglyceric acid phosphorylation occurs, and oxidative decarboxylation does not occur.
