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.

II. Overall Structure . The D1 and D2 subunits of each monomer form the center of the complex, each comprising five membrane spanning helices. On either side of the D1 / D2 center, are subunits CP43 and CP47, having six transmembrane helices oriented similarly to the N-terminal domains of the PsaA and PsaB subunits of photosystem I (see tutorial on PSI).

This worksheet describes the process of chemiosmosis that occurs in the chloroplasts during photosynthesis. It includes a coloring diagram of the membrane with the electron acceptors, transport chain, and ATP synthase. Students read about the path electrons take that ultimately results in the production of ATP.

A diagram of the light reaction of phosynthesis where you can label the steps. It shows photosystem 1 and photosystem 2, and the electron transport chain. 2 dagar sedan · Each photosystem consists of a light-harvesting complex and a core complex. Each core complex contains a reaction centre with the pigment (either P 700 or P 680) that can be photochemically oxidized, together with electron acceptors and electron donors.

Photosystem II occurs with two series of enzymes followed by Photosystem I in order to create energy for a plant1. The picture shows a top view of photosystem II (PDB entry 1s5l ), showing all of the light-absorbing molecules inside. The central chlorophyll molecule of the reaction center is shown with the arrow (notice the second reaction center in the bottom half--photosystem II is composed of two identical halves). Main difference photosystem 1 vs 2.

Photosystem II is the first link in the chain of photosynthesis. It captures photons and uses the energy to extract electrons from water molecules. These electrons are used in several ways. First, when the electrons are removed, the water molecule is broken into oxygen gas, which bubbles away, and hydrogen ions, which are used to power ATP synthesis.
