Question

In $C_4$ plants, the process by which $C_4$ acid is converted into $C_3$ acid in the cells of the bundle sheath is known as:

• A. Carboxylation
• B. Regeneration
• C. Reduction
• D. Decarboxylation

Answer 1

The correct option is D Decarboxylation

In $C_4$ plants , the process by which $C_4$ acids are converted into $C_3$ acids in the cells of the bundle sheath is known as decarboxylation. Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (${\mathrm{CO}}_2$ ). Enzymes that catalyze decarboxylation are called decarboxylases.
