C3 and C4 plants differ through a. e. cyclic vs non-cyclic photophosphorylation. different reaction centres that collect photon energy. the reduction of NADP+ the activity of PEP to combine with CO2. different methods of breaking H2O into O, 2e" and 2H¹. C

During oxygenic photosynthesis in plants, the hydrogen atoms that end up in product carbohydratemolecules are coming from which of the following substrate molecules?A. water molecules (H2O)B. sucrose sugars (C12H22O11)C. carbon monoxide (CO)D. glucose sugars (C6H12O6)E. carbon dioxide (CO2)

Mark ALL that are true for cyclic photophosphorylation.

Which of the following statements is TRUE?

In the linear light reaction... Select one: a.Electrons exiting PSII leave the system when NADP+ reductase adds them to NADP+ b.Electrons exiting PSI leave the system when NADP+ reductase adds them to NADP+ c.Electrons exiting PSI travel down the ETC

Despite CAM photosynthesis having a comparatively higher water use efficiency relative to C3 and C4 plants, its distribution is restricted primarily to desert succulents. In terms of water use efficiency, explain why CAM photosynthesis has not spread more widely.
