Photosynthesis 1. The steps of photosynthesis are outlined in the diagram. For each of the steps below, identify what starts the reaction, what is created, and where it takes place. a. Light Dependent Reactions - chloroplast and within the thylakoid membrane. Light enters photosystem 2, water

Photosystem I is a plastocyanin-ferredoxin oxidoreductase which uses light energy to transfer an electron from the donor P700 chlorophyll pair to the electron acceptors A0, A1, FX, FA and FB in turn. The function of PSI is to produce the NADPH necessary for the reduction of CO2 in the Calvin-Benson cycle.

2016-07-20 1. The thylakoid membrane is composed of a phospholipid bilayer (color phospholipids "B" light blue) with an interior space and an exterior, called the stroma. Photosynthesis takes place in two systems: photosystem I (P1) and photosystem II (P2). 2. The first event is the capturing of light energy (color E orange) by pigments in the membrane This video explains: (5 minutes video)For captions, Please click on the 'CC' button next to the gear icon at the right-hand-side bottomDefinition of Photosy - Photosystem I reduction of NADP+ oxidation of electron transport chain between the two photosystems 2017-03-01 Photosystem II (or water-plastoquinone oxidoreductase) 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 2017-11-27 Modern cells capture light using photosystem proteins, such as the one pictured here from PDB entry 1s5l . These photosystems use a collection of highly-colored molecules to capture light. These light-absorbing molecules include green chlorophylls, which are composed of a flat organic molecule surrounding a magnesium ion, and orange carotenoids, which have a long string of carbon-carbon … Photosystem II 2 Last updated; Save as PDF Page ID 486; References; Photosystem is the form of pigments on the thylakoid membrane1.

Difference # Photosystem II (PS II): 1. Photosystem II (PS II) is involved only in non-cyclic photophosphorylation. 2. 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.
