Mr X Ten Differences Betwixt Photosystem I As Well As Photosystem 2 (Psi Vs Psii)
Photosynthesis takes house inward 2 steps: Light reaction in addition to Dark reaction. Light reaction occurs inward the grana of chloroplast. The chlorophyll absorbs the calorie-free energy. Hence the chlorophyll is called a photosystem or paint system. Chlorophylls are of dissimilar types in addition to they absorb dissimilar wavelengths of light.
Accordingly chlorophylls be 2 photosystems, namely photosystem I (PS I) in addition to photosystem II (PS II). Both photosystem (PS I in addition to PS II) are affected past times calorie-free amongst wavelengths shorter than 680nm (nanometer), piece photosystem I is affected past times calorie-free amongst wavelengths longer than 680nm.

Photosystem I includes the next pigments: Chlorophyll b, Chlorophyll -a 670, Chlorophyll -a 680, Chlorophyll -a 695, Chlorophyll -a 700 or P700, Carotenoids.
In photosystem I, P700 cast of chlorophyll a is the active reaction centre.
Photosystem II includes the next pigments: Chlorophyll b, Chlorophyll - a 660, Chlorophyll -a 670, Chlorophyll -a 680 or P680, Chlorophyll -a 695, Chlorophyll - a 700 or P700, Phycobilins, Xanthophylls.
In photosystem II, P680 cast of chlorophyll a is the active reaction centre.
Photosystem I in addition to Photosystem II (PS I vs PS II)
Photosystem I (PS I) | Photosystem II (PS II) |
PS I is located at the outer surface of the grana thylakoid membrane (non appressed granal regions in addition to stroma lamella). | PS II is located at the inner surface of the grana thylakoid membrane (appressed granal region). |
The photocentre or reaction centre is P700. | The photocentre is P680. |
PS I has an iron-sulphur (FeS) type reaction centre (or type I) | PS II has a quinone type reaction centre (also known every 2d Q-Type or type II) |
The nitty-gritty complex of PSI is composed past times a smaller publish of proteins ( fifteen subunits) than PSII | The nitty-gritty of PSII is a multi-subunit complex composed of close 25-30 subunits. |
Pigments absorb longer wavelengths of calorie-free (>680nm). | Pigments absorb shorter wavelengths of calorie-free (<680nm). |
Rich inward chlorophyll a than chlorophyll-b | Rich inward chlorophyll b than chlorophyll-a |
Participates inward cyclic every 2d good as | Participates exclusively inward non-cyclic photophosphorylation. |
It is non associated amongst photolysis of water. | It is associated amongst photolysis of water. |
PS I generates a rigid reducing agent (reducing NADP+ to NADPH) in addition to a weak oxidant | PS II is the rigid oxidant (capable of oxidizing H2O) in addition to a weak reductant |
Main business office is ATP synthesis inward cyclic photophosphosphorylation in addition to NADPH synthesis inward non-cyclic photosynthesis. | Main functions are ATP synthesis in addition to hydrolysis of water. |
