During C3 cycle (calvin cycle) 3 phases continue, namely carboxylation, Reduction & regeneration. During reduction or fixation phase, each CO2 molecule require one mole of ATP and one mole of NADPH.
When one CO2 molecule is fixed as one molecule of triose phosphate, which of the following photochemically made, high energy chemical intermediates are used in the reduction phase?

Which of the following statements about RuBisCO is true?
Observe the given figure. Identify the different stages labelled with alphabets by selecting the correct option. 
Which one of the following products diffuses out of the chloroplast during photosynthesis?
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:
