The substrate of Photorespiration is : A)Fructose B)Pyruvic acid C)Glycolate D)Glucose
Option C) Glycolate is the major substrate for photorespiration. The enzymes of glycolate metabolism, e.g. glycolate oxidase and catalase, are present in substantial quantities in leaf extracts from both high and low capacity plants. Glycolate has been detected in leaves of both types of plants.
