Photosystem is the form of pigments on the thylakoid membrane1. It collects energy over the wavelengths and concentrates it to one molecule which uses the energy to pass one of its electrons on to a series of enzymes1. Photosystem II occurs with two series of enzymes followed by Photosystem I in order to create energy for a plant1.

Here … Photosystem II is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria. Within the photosystem, enzymes capture photons of light to energize electrons that are then transferred through a variety of coenzymes and cofactors to reduce plastoquinone to plastoquinol. The energized electrons are replaced by oxidizing water to form hydrogen ions and molecular oxygen.

There are two types of photosystems found in most plants: photosystem I (PSI) and photosystem II (PSII). Each photosystem is made of two components: 1) antenna complex that consists of 300-400 chlorophyll a and b molecules and other accessory pigments such as carotenoids and 2) reaction center that consists of one or more chlorophyll molecules with a primary electron acceptor.

4. Photosystem II. Photosystem II is a group of proteins and pigments that work together to absorb light energy and transfer electrons through a chain of molecules until it finally reaches an electron acceptor. Photosystem II has a pair of chlorophyll molecules, also known as P680 as the molecules best absorb light of the wavelength 680 nm.

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. (2–5) Can the genomic and proteomic data obtained from investigating current organisms paint a precise picture of the photosystem I (PSI) as a plastocyanin–ferredoxin oxidore-ductase and the F-ATPase as a Protonmotive force (pmf)-driven ATP synthase (Fig. 1). Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin . 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.
