Answer: STEPS 1,2,3 THE SAME except chlorophyll a is (P700) 4)the electron from
photosystem II will fill this electron hole in chlorophyll a(P700) 5)(e-)
->primary electron acceptor, IT CAN TAKE 1 OF 2 PATHS, PATH 1]
electrons(e-) are diverted back towards the CYTOCHROME COMPLEX in order to
generate more ATP. PATH 2]electrons(e-) -> FERADOXIN(Fd) -> NADP REDUCTASE.
the NADP reductase will generate NADPH (final electron acceptor)

Cyclic electron flow around PSI or cyclic photophosphorylation is the photosynthetic process which recycles the reducing equivalents produced by photosystem I in the stroma towards the plastoquinone pool. Through the activity of cytochrome b (6)f which also transfers protons across the membrane it promotes the synthesis of ATP.
Cyclic electron flow around photosystem I via chloroplast NAD(P)H dehydrogenase (NDH) complex performs a significant physiological role during photosynthesis and plant growth at low temperature in rice.

The reactions involve two types of electron flow in the thylakoid membrane. While linear electron transport generates both ATP and NADPH cyclic electron transport around photosystem I (PS I) is...
This linear electron flow is driven by two photochemical reactions that function in series. The cytochrome b6f complex mediates electron transport between the two photosystems and generates the...
Cyclic Electron Flow The light dependent reactions begin with a structure called Photosystem I. Photosystem I is an integral membrane protein complex on the thylakoid membrane that absorbs sunlight with a photosynthetic pigment. The optimal wavelength that this pigment absorbs is P700. Within PS1 there is what is called the reaction center.
