Photosynthesis is composed of two main parts (light-dependent and light-independent). Photosystem I (PS I) and photosystem II (P
S II) are alike in many ways. How does photosystem I and photosystem II differ from one another? A) PS I produces glucose while PS II produces ATP. B) PS I occurs in the stroma while PS II takes place in the thylakoid membranes. C) PS I is a light-independent reaction while PS II is a light-dependent reaction. D) PS I absorbs the longer wavelength of light while PS II absorbs a shorter wavelength of light.
Photosystem I and II differ from each other in following ways –
a) Light absorbed in PS I has a longer wavelength as compared to light absorbed in PS II. PS I absorbs light of wavelength 700 nm while PS II absorbs wavelength of 680 nm
b) PS I receives electron through the ETC after the PS II completion. While PSII gets its electron form splitting of water.
