Photosynthesis In Higher Plants

Question

Wired Faculty App

Photorespiration in C₃ plants starts from:

phosphoglycerate

phosphoglycolate

glycerate

glycine

Solution

B.

phosphoglycolate

In the process of photorespiration oxygen combines with RuBP (Ribulose- biphosphate) in chloroplast as following

O₂ + RuBP $\overset{Rubisco}{\to}$ 3- Phosphoglycerate + $↴$

2- Phosphoglycerate $\to$ CO₂

Phosphoglycolate enters in peroxisomes and is finally converted to CO₂.
