The reaction centre in PS II has an absorption maxima at
The reaction centre in PS II has an absorption maxima at
- 780 nm
- 680 nm
- 700 nm
- 660 nm
Solution
The pigments involved in photochemical reactions are organised into two discrete photochemical light harvesting complexes (LHC) within the Photosystem I (PS I) and Photosystem II (PS II).
- In PS I, the reaction centre chlorophyll-a has an absorption peak at 700 nm, hence is called P700.
- In PS II the reaction centre chlorophyll-a has an absorption maxima at 680 nm, and is called P680.
