Cyclic photophosphorylation is performed by PS-I only. In this process, an electron expelled by the excited photocentre, ie, P700 is returned to it after passing through a series of electron carriers. PS-I is located on both the non-appressed part of grana thylakoids as well as stroma thylakoids, while PS-II is located in the appressed part of grana thylakoids only, stroma thylakoids lack PS-II.

How many molecules of ATP and NADPH are required for every molecule of $\mathrm{CO}_2$ fixed in the Calvin cycle?
2024medium
Given below are two statements: Statement I: In $\mathrm{C}_3$ plants, some $\mathrm{O}_2$ binds to RuBisCO, hence $\mathrm{CO}_2$ fixation is decreased. Statement II: In $\mathrm{C}_4$ plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration. In the light of the above statements, choose the correct answer from the options given below:
