When only light of wavelength beyond 680 nm are available then which of the following is not occur :-
Open in App
Solution
The correct option is A Absorption of light
When the wavelengths are beyond 680 nm then it belongs to Photosystem 1 which has wavelength 700 nm. Electrons are transported from photosystem 2 i.e.' wavelength 680 nm to 700 nm which extrudes out energy which is absorbed by antenna molecules of photosystem 2 and then carries to two different carriers and releases energy. There is no step regarding the fixation of carbon dioxide thus no oxygen production.So, the correct option is 'Release of CO2'.
