Question

Choose the correct statement.

• A. The $C _{4}$ plants do not have RuBisCO.
• B. Carboxylation of RuBP leads to the formation of PGA and phosphoglycolate.
• C. Carboxylation of phosphophenol pyruvate results in the formation of $C _{4}$ acids.
• D. Decarboxylation of $C _{4}$ acids occurs in the mesophyll cells.

Answer 1

Answer: (C)

RuBisCO enzyme is present in the bundle sheath cells of $C _{4}$ plants. Oxygenation of RuBisCO forms PGA and phosphoglycolic acid. Decarboxylation of $C _{4}$ acids takes place in bundle sheath cells.
