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
Correct Answer: B
Solution :
Oxygenic photosynthetic organism like green plants and blue-green algae have two type of photosystem called PS-1 and PS-II. In PS-I chlorophyll absorb maximum light at wavelength 700 nm. Thus reaction centre is P700 and PS-II chlorophyll absorb maximum light at wavelength 680 nm, thus reaction centre is 680- PS-II takes up electrons from water and returning to its unexcited ground state because hydrolysis of \[{{H}_{2}}O\] occurs in PSII. So photolysis of \[{{H}_{2}}O\]takes place in PS-II during light reaction of photosyntheis.
