Many versions of the Z-scheme are available in the literature.This particular diagram was developed by Wilbert Veit and Govindjee, 2000, and can be also found at molecadv.com. The electrons from photosystem I are then passed in a series of redox reactions through the protein ferredoxin. The electrons finally reach NADP +, reducing them to NADPH. Reaction.
Photosystem II (PS II) donates electrons to photosystem I where NADP+ is reduced. 3. This system is responsible for the photolysis of water and involves the evolution of molecular oxygen. 4. 6 CO 2 + 6 H 2 O → (in the presence of sunlight) C 6 H 12 O 6 + 6 O 2 Photosynthesis Diagram According to the diagram of photosynthesis, the process begins with three most important non-living elements: water, soil, and carbon dioxide. Photosystem II or PS II is the membrane-embedded-protein-complex, consisting of more than 20 subunits and around 100 cofactors. The light is absorbed by the pigments such as carotenoids, chlorophyll, and phycobilin in the region known as antennae and further this excited energy is transferred to the reaction center.

Under certain conditions, the photoexcited electrons take an alternative path called cyclic electron flow, which uses photosystem I (P700) but not photosystem II (P680). This process produces no NADPH and no O 2, but it does make ATP. This is called cyclic photophosphorylation. Three-dimensional structure of cyanobacterial photosystem I at 2.5 Å resolution. Nature 411, 909-917 (2001). Deisenhofer, J. and Michel, H., Epp, O., Sinning, I. and Michel, H. Crystallographic refinement at 2.3 Å resolution and refined model of the photosynthetic reaction centre from Rhodopseudomonas viridis.
This pathway occurs in the thylakoid membranes and requires participation of two light-gathering units: photosystem I (PS I) and photosystem II (PS II). · 2.
