Photophosphorylation in chloroplast is most similar to the
1 Trancription in nucleus
2 Mitochondrial oxidative phosphorylation
3 Mitochondrial glycolysis
4 Ribosomal translation
Explanation:
ATP synthesis in chloroplasts is called photophosphorylation. It is very similar to oxidative phosphorylation in mitochondria due to the common steps involved. Both possess a H+ gradient, both bear an ETS, similar mechanisms are carried out.

Photosynthesis cannot continue for long if during light reaction, only cyclic photophosphorylation takes place. This is because
1 There is unidirectional cyclic movement of the electrons
2 There is no evolution of \(\mathrm{O}_{2}\)
3 Only ATP is formed, \(\mathrm{NADPH}^{+}+\mathrm{H}^{+}\)is not formed
4 Photosystem I stops getting excited at a wavelength of light beyond \(680 \mathrm{~nm}\)
Explanation:
Assimilatory power, i.e., ATP and \(\mathrm{NADPH}_{2}\) are produced during light reaction of photosynthesis. As only cyclic photophosphorylation takes place only ATP is formed and photosynthesis cannot continue for long because in absence of \(\mathrm{NADPH}_{2}\). Dark reaction of photosynthesis do not take place.
