Vedclass · Answer

(A) In the Calvin cycle,the reduction phase involves the conversion of $3$-phosphoglycerate ($3$-$PGA$) to glyceraldehyde $3$-phosphate (triose phosphate).For the fixation of one molecule of $CO_2$,the reduction phase requires $1$ molecule of $ATP$ (for phosphorylation) and $1$ molecule of $NADPH$ (for reduction).However,the overall stoichiometry for the production of one molecule of triose phosphate from $3$ molecules of $CO_2$ requires $6$ $ATP$ and $6$ $NADPH$ in the reduction phase.Therefore,for the fixation of a single $CO_2$ molecule,the requirement is $1$ $ATP$ and $1$ $NADPH$ specifically for the reduction step.

When one $CO_2$ 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?
