A) 1:1
B) 2:1
C) 3:2
D) 3:4
Correct Answer: B
Solution :
During photorespiration, in peroxisome 2-molecules of glycine \[(2{{H}_{2}}NC{{H}_{2}}-C{{O}_{2}})\] are transferred into mitochondrion, where they are converted into 1-molecule of serine \[(HOC{{H}_{2}}-{{H}_{2}}NCH-C{{O}_{2}}).\] Thus, the ratio between 2C and 3C intermediates having \[-N{{H}_{2}}\]group is 2:1.
