Photosynthesis In Higher Plants

Question
CBSEENBI11025150
Wired Faculty App

Photorespiration in C3 -plants starts from :

  • glycine

  • glycerate

  • phosphoglycolate

  • phosphoglycerate

Solution

C.

phosphoglycolate

Photorespiration in C3 -plants starts from phosphoglycolate. Phosphoglycolate is formed in chloroplast which represents the source of carbon dioxide released in photorespiration. Its phosphate group is first hydrolyzed away by a specific phosphatase found in chloroplasts of C3 -plants releasing Pi and glycolic acid. The glycolate then moves out of chloroplasts into the adjacent peroxisomes.
