Document Summary
And by primary electron acceptor reduced to original p680 with an electron from water. The light reactions which capture light energy and synthesis atp and nadph, the calvin cycle is the reduction of carbon dioxide and production of carbohydrates. Nadp+ is reduced to nadph in the light reactions in the calvin cycle nadph is able to reduce other molecules. There are two photosystems involved antenna complex is the same but the reaction centre differs p680 in photosystem ii has an absorption peak at. 680nm, in photosystem i its p700 at 700nm they function the same so once excited the reaction centre chlorophyll donates electron to primary acceptor. Photosystem ii, photon funnelled by antenna complex to p680, excited p680* oxidized to p680+ by primary acceptor, p680+ reduced back to p680 oxygen evolving complex pulls electrons from water and gives to p680+ Electron transport is a series of redox reactions.
