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 :
Green plants and algae use two type of photo-system called PS-I and PS-II. In PS-I chlorophyll absorb maximum at 700 nm wavelength of light thus reaction centre is \[{{P}_{700}}\] and PS-II absorb maximum 680 nm wavelength of light thus reaction centre is \[{{P}_{680.}}{{P}_{680}}\](PS-II) extracts an electron from water, returning to its unexcited state because hydrolysis of \[{{H}_{2}}O\] occurs in PS-II. So, C2 evolved in PS-II come from water.
