The substrate for photorespiration is :
glycolate
acetyl Co-A
pyruvic acid
glucose
A.
glycolate
Photorespiration is a kind of respiration that occurs in photosynthetic cells only. In this process chloroplast, mitochondria and peroxisomes are involved. The substrate for photorespiration is glycolate formed in the chloroplast. It is converted enzymatically into glyoxalate in peroxisome which further changes into glycine. In mitochondria glycine changes into serine. It is the characteristic feature of C3 plants.
