During both CAM and C₄ photosynthesis, what is the role of the PEP carboxylase enzyme?

Question

Quizplus · Accepted Answer

The role of PEP carboxylase enzyme in both CAM and C4 photosynthesis is to capture CO₂ in the form of 4-carbon organic acids, such as malate or oxaloacetate. This is important because the 4-carbon organic acids are transported to the bundle sheath cells to release CO₂ for the Calvin cycle, while minimizing the loss of water through transpiration in hot and dry conditions. Therefore, option D is the best choice.
