For cyclic Photophosphorylation to occur, aerobic conditions with optimum light intensity and presence of enzymes would be apt.

During photophosphorylation electron is lost from?
1 Chlorophyll ‘a’
2 Chlorophyll ‘b’
3 Chlorophyll ‘a’ and ‘b’
4 Electron loss never occurs
Explanation:
During light reaction, suitable wavelength of light excites an electron from the reaction centre i.e. chlorophyll a (680 or 700)

In a crop field a weedicide is used to remove weeds in order to increase the yield. But the effect of this weedicide is that, it blocks electron transport from photosystem II to photosystem I. This will result in
1 Enhancement of dark reaction.
2 Failure of ATP synthesis.
3 Lack of reduction of NADP + .
4 Both (2) and (3).
Explanation:
During the electron transport from photosystem II to photosystem I, ATP is synthesized and NADP \(_{\mathrm{z}}\) is reduced to NADPH. So, the blockage of electron transport will stop ATP synthesis and the reduction of \(\mathrm{NADP}^{+}\)to NADPH.
