Question

Formation of phosphoglyceraldehyde from phosphoglyceric acid is

• A. Hydrolysis
• B. Oxidation
• C. Reduction
• D. Electrolysis

Answer 1

Answer: (C)

Reduction

A) Hydrolysis is not involved in the formation of phosphoglyceraldehyde from phosphoglyceric acid.

B) Oxidation is not involved in the formation of phosphoglyceraldehyde from phosphoglyceric acid.
C) 3-Phosphoglyceric acid is a carboxylic acid and phosphoglyceraldehyde is an aldehyde. Aldehydes are formed due to the reduction of carboxylic acids. So, the formation of phosphoglyceraldehyde from phosphoglyceric acid takes place through reduction.

D) Electrolysis does not take place in plants.

So the correct answer is 'Reduction'.
