Vedclass · Answer

(A) The Calvin cycle consists of three main stages: Carboxylation,Reduction,and Regeneration.$1$. Carboxylation: $CO_2$ combines with a $5$-carbon sugar called Ribulose $1,5$-bisphosphate $(RuBP)$ (represented by $P$) to form a $3$-carbon acid,$3$-phosphoglycerate ($3$-$PGA$) (represented by $R$).$2$. Reduction: $3$-$PGA$ is converted into Triose phosphate (represented by $Q$) using $ATP$ and $NADPH$.$3$. Regeneration: Triose phosphate is used to regenerate $RuBP$ to continue the cycle.Therefore,$P$ is Pentose sugar $(RuBP)$,$R$ is $3$-carbon acid ($3$-$PGA$),and $Q$ is Triose sugar (Triose phosphate).

The stages of the Calvin cycle are given below. Identify $P, Q$ and $R$.
