Q. The radio between 2-carbon and 3-carbon intermediates having $–NH_{2}$ group formed in photosynthetic oxidation cycle is

A) 1 : 1
B) 2 : 1
C) 3 : 2
D) 3 : 4
Explanation

During photorespiration in Peroxisome, two molecules of glycine ($2H_{2}NCH_{2} - CO_{2}$) are transferred into mitochondrion, where they are converted into one molecule of serine ($HOCH_{2} - H_{2}NCH - CO_{2}$). Thus, the ratio between 2C and 3C intermediates having $–NH_{2}$ group is 2:1.
