Vedclass · Answer

(B) Photorespiration,also known as the $C_2$ cycle,occurs when the enzyme $RuBisCO$ acts as an oxygenase instead of a carboxylase. This process begins with the oxygenation of $RuBP$ (Ribulose$-1,5-$bisphosphate) to form one molecule of $3$-phosphoglycerate and one molecule of $2$-phosphoglycolate. The $2$-phosphoglycolate is then dephosphorylated to form glycolate. Therefore,glycolate acts as the primary substrate that enters the photorespiratory pathway in the peroxisomes.
