Photosynthesis in Higher Plants

The substrate for photorespiration is

  1. (A)phosphoglyceric acid
  2. (B)glycolate
  3. (C)serine
  4. (D)glycine

The NCERT line that answers it

Verbatim line

Here the RuBP instead of being converted to 2 molecules of PGA binds with $O_2$ to form one molecule of phosphoglycerate and phosphoglycolate (2 Carbon) in a pathway called photorespiration.

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly states that RuBP binds with O₂ to form phosphoglycolate in photorespiration, and glycolate is the substrate derived from phosphoglycolate in the photorespiratory pathway.
