Photorespiration in ` C_3` - plants starts from

Options

A. Phosphoglycerate
B. Phosphoglycolate
C. glycerate
D. Glycine

Answer

B

Explanation

In the process of photorespiration oxygen combines with RUBP (Ribulose - biphosphate) in chloroplast as following
`O_2 RUBP overset("Rubisco") to 3 - "phosphoglycerate" + 2- "phosphoglycolate" to CO_2`
Phosphoglycolate enters in peroxisomes and is finally converted to `CO_2`
