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

During photorespiration, the oxygenation reaction of the $RuBisCo$ enzyme produces:

The structure known as a peroxisome is associated with which of the following processes?

Give scientific reasons: $(1)$ Photorespiration does not take place in $C_4$ plants.

Photorespiration is a characteristic of which plant?

$A$ cyclic process is occurring in $C_3$ plants,which is light-dependent and requires $O_2$. This process does not produce energy; rather,it consumes energy. Where does it occur?
