Which of the following is a disadvantage of C ₄ photosynthesis relative to C ₃ photosynthesis? A) inability of rubisco to obtain O ₂ B) C₄ plants need energy to move fixed carbon compounds into bundle sheath cells C) need for stomata to close to conserve H ₂O D) need for energy to move H ₂O into bundle sheath cells E) inability of ATP synthase to utilize H ⁺ gradient for energy

Question

Quizplus · Accepted Answer

C4 photosynthesis requires additional energy to shuttle fixed carbon compounds into bundle sheath cells for the Calvin cycle, unlike C3 photosynthesis which occurs directly in the mesophyll cells without the need for such energy expenditure.
