Write five difference between ps1 &ps2
Answers
Answer:
FIVE DIFFERENCE BETWEEN PS1 AND PS2 ARE AS FOLLOWS :--
PS1
➡️ PS I uses light energy to convert NADP+ to NADPH2. It involves the P700, chlorophyll and other pigments.
➡️ The pigments in the photosystem 1 absorb longer wavelengths of light which is 700 nm (P700).
➡️ No photolysis occur.
➡️ PS 1 contains chlorophyll A-670, chlorophyll A-680, chlorophyll A-695, chlorophyll A-700, chlorophyll B, and carotenoids.
➡️ The PSI is made up of two subunits which are psaA and psaB
PS2
➡️ PS II is the protein complex that absorbs light energy, involving P680, chlorophyll and accessory pigments and transfer electrons from water to plastoquinone and thus works in dissociation of water molecules and produces protons (H+) and O2.
➡️ The pigments in the photosystem2 absorb shorter wavelengths of light which is 680 nm (P680).
➡️ Photolysis occurs in this system.
➡️ PS 2 contains chlorophyll A-660, chlorophyll A-670, chlorophyll A-680, chlorophyll A-695, chlorophyll A-700, chlorophyll B, xanthophylls and phycobilins.
➡️ The PS II is made up of two subunits made up of D1 and D2.
