Question

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

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