The reaction centre in PS II has an absorption maxima at
Options
- A780 nm
- B680 nm
- C700 nm
- D660 nm
Correct answer
B. 680 nm
Step-by-step 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.
