The glycoiate produced during photorespiration enters
Question
The glycoiate produced during photorespiration enters
Solution
The glycolate produced during photorespiration enters the peroxisomes. In the peroxisomes, glycolate is converted into glyoxylate through the action of glycolate oxidase. This process releases hydrogen peroxide (H2O2), which is neutralized by catalase, another enzyme present in the peroxisomes. The glyoxylate is then converted into glycine in the mitochondria, and this is the first step of the photorespiratory pathway.
