Plants using the C₄ photosynthetic pathway

Question

Quizplus · Accepted Answer

Plants using the C₄ photosynthetic pathway divide photosynthesis between mesophyll and bundle sheath cells. This allows for a more efficient carbon fixation process and reduces photorespiration. Choice A is incorrect because plants using the C₄ photosynthetic pathway use an enzyme called PEP carboxylase to initially capture CO₂, rather than rubisco. Choice B is also incorrect because plants using the C₄ photosynthetic pathway actually have higher rates of photosynthesis in high light and high temperature conditions than plants using the C₃ pathway. Choice D is incorrect because plants using the C₄ photosynthetic pathway are found in a variety of plant forms, including grasses and some succulents.
