You are evaluating novel varieties of C₃ rice that express PEP carboxylase and rubisco in both mesophyll and bundle-sheath cells for a project to develop rice plants that are capable of C₄ photosynthesis. Your MOST promising candidates are those for which the enzyme levels of:

Question

Quizplus · Accepted Answer

C4 photosynthesis, which is being referenced here, typically involves higher levels of PEP carboxylase in the mesophyll cells to capture carbon dioxide. This is then transported to the bundle-sheath cells where rubisco operates in a CO2-rich environment, reducing photorespiration. Therefore, option B aligns with the characteristic distribution of these enzymes in C4 photosynthesis.
