How many molecules of glycine are required to release one $CO_{2}$ molecule in photorespiration?

Photorespiration is stimulated by the presence of:

Peroxisomes,in plant cells,are involved in

In photorespiration,glycolate is converted to $CO_2$ and serine in:

Given below are two statements:
Statement $I$: In $C_3$ plants,some $O_2$ binds to $RuBisCO$,hence $CO_2$ fixation is decreased.
Statement $II$: In $C_4$ plants,mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration.
In the light of the above statements,choose the correct answer from the options given below:

In photorespiration,what is the role of peroxisome?
