Vedclass · Answer

(A) In the Calvin cycle (dark reaction),the primary carboxylation step involves the fixation of $CO_2$ into a $5$-carbon compound called Ribulose $1,5$-bisphosphate $(RuBP)$.This reaction is catalyzed by the enzyme $RuBisCO$.The resulting product is an unstable $6$-carbon intermediate,which immediately breaks down into two molecules of $3$-phosphoglyceric acid ($3$-$PGA$).Since $3$-$PGA$ is the first stable compound formed in this process,it is considered the first stable product of the dark reaction.
