The energy wastage occurs during

During photorespiration,phosphorylation as well as oxidation both occur in:

What effect would occur on photosynthesis if the amount of oxygen in the atmosphere decreases?

Match the following regarding the photorespiration pathway:

Column-$I$	Column-$II$
$(1)$ Molecule transport from chloroplast to peroxisome	$(p)$ Glycine
$(2)$ Molecule transport from peroxisome to mitochondria	$(q)$ Serine
$(3)$ Molecule transport from mitochondria to peroxisome	$(r)$ Glycerate
$(4)$ Molecule transport from peroxisome to chloroplast	$(s)$ Glycolate

$A$ cyclic process occurs in $C_3$ plants,which is light-dependent and requires $O_2$. This process does not produce energy; rather,it consumes energy. What are the end products of this process?

Which one of the following is wrong in relation to photorespiration?
