Photosynthesis In Higher Plants Question 1
Question: The reaction centre in PS II has an absorption maxima at
(1) 700 nm
(2) 680 nm
(3) 660 nm
(4) 780 nm
Show Answer
Answer: (2) 680 nm
Explaination-
In photosystem l, the reaction centre has an absorption peak at 700 nm (red light), hence is called P700 and in PS ll, the reaction centre has an absorption peak at 680 nm (red light), hence is called P680.
