The correct Answer is:
To determine the process involved in the formation of phosphoglyceraldehyde from phosphoglyceric acid, we need to analyze the chemical transformation taking place between these two compounds. ### Step-by-Step Solution: 1. **Identify the Compounds**: - Phosphoglyceric acid is a carboxylic acid, characterized by the presence of a carboxyl (-COOH) group. - Phosphoglyceraldehyde is an aldehyde, which contains a carbonyl group (C=O) at the end of the carbon chain. 2. **Understand the Transformation**: - The conversion of a carboxylic acid (phosphoglyceric acid) to an aldehyde (phosphoglyceraldehyde) involves a change in the functional group. 3. **Determine the Type of Reaction**: - The process of converting a carboxylic acid to an aldehyde typically involves reduction. Reduction is defined as the gain of electrons or hydrogen, or the loss of oxygen. - In this case, the reduction of phosphoglyceric acid involves the addition of hydrogen, which converts the carboxylic acid group to an aldehyde group. 4. **Evaluate the Options**: - (a) Hydrolysis: This involves the breakdown of a compound in the presence of water, which is not applicable here. - (b) Oxidation: This is the opposite of reduction and would not apply in converting a carboxylic acid to an aldehyde. - (c) Reduction: This is the correct process, as it involves the conversion of the carboxylic acid to an aldehyde through the addition of hydrogen. - (d) Electrolysis: This process does not occur in plants and is not relevant to this transformation. 5. **Conclusion**: - The correct answer is (c) Reduction.
