Q. In photosynthesis, what does occur in PS-II?
A) It takes longer wavelength of light and $e^{-}$from $H_{2}O$
B) It takes shorter wavelength of light and $e^{-}$ from $H_{2}O$
C) It takes longer wavelength of light and $e^{-}$ from NADP
D) It takes shorter wavelength of light and $e^{-}$ from NADP
Explanation
PS-II absorbs maximum 680 nm wavelength of light, thus reaction centreis $P_{680}$.$P_{680}$ (PS-II) extracts an electron from water, returning to its unexcited state because hydrolysis of water occurs in PS-II. Oxygen evolved in PS-II comes from water.
