Vedclass · Answer

(C) Photorespiration is a process that occurs in $C_3$ plants when the enzyme $RuBisCO$ acts as an oxygenase instead of a carboxylase.In this process,$RuBP$ (a $5$-carbon compound) reacts with $O_2$ instead of $CO_2$.This reaction is known as oxygenation,which is the first step of the photorespiratory pathway.As a result,$RuBP$ is converted into one molecule of $3$-phosphoglycerate ($3$-$PGA$) and one molecule of phosphoglycolate ($2$-carbon compound).
