RECOVERY OF PHOTOSYNTHESIS AND PHOTOSYSTEM-II

PS 1 contains chlorophyll B, chlorophyll A-670, Chlorophyll A-680, chlorophyll A-695, chlorophyll A-700 and carotenoids. Se hela listan på differencebetween.com The primary function of the photosystem I in NADPH synthesis, where it receives the electrons from PS II, and the photosystem II is in the hydrolysis of water and ATP synthesis. Core Composition in the PSI is made up of two subunits which are psaA and psaB, and PS II is made up of two subunits made up of D1 and D2. 2021-04-17 · Photosystems I and II The structural and photochemical properties of the minimum particles capable of performing light reactions I and II have received much study. Treatment of lamellar fragments with neutral detergents releases these particles, designated photosystem I and photosystem II, respectively. Photosystem I (PS-I) and photosystem II (PS-II) are two multi-subunit complexes that laid inside the thylakoid membrane of chloroplast and involved in the process of photosynthesis. A photosystem possesses an antenna complex (contains around 200-300 light-harvesting pigment molecules) and a reaction centre.

Chlorophyll is the pigment involved in capturing light energy. PS 1 contains chlorophyll B, chlorophyll A-670, Chlorophyll A-680, chlorophyll A-695, chlorophyll A-700 and carotenoids. Photosystem I or PS I and Photosystem II or PS II are the protein-mediated complex, and the main aim is to produce energy (ATP and NADPH2), which is used in Calvin cycle, the PSI uses light energy to convert NADP+ to NADPH2. It involves the P700, chlorophyll and other pigments, while PS II is the complex that absorbs light energy, involving P680, chlorophyll and accessory pigments and transfer electrons from water to plastoquinone and thus work in dissociation of water molecules and produces Photosynthesis - Photosynthesis - Photosystems I and II: The structural and photochemical properties of the minimum particles capable of performing light reactions I and II have received much study.
