In chloroplast, both light and dark reaction of photosynthesis takes place. In the disc of thylakoid, the light reaction takes place where water is oxidized to release oxygen. The transfer of electrons is facilitated by plastoquinone from PS-II to Cytb6f complex, in the light reaction. The electrons which are freed from water a transfer to ATP and NADPH. The dark reaction occurs outside the thylakoid, in the stroma and cytoplasm, and in this reaction, the energy from ATP and NADPH are utilized to fix carbon dioxide. Sugar molecules and other organic molecules which are necessary for the cell function in metabolism are products of this reaction.

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:
