In the C2 oxidative photosynthetic cycle, also known as the photorespiratory pathway, glycolate is produced in the chloroplasts during the oxygenation of Ribulose-1,5-bisphosphate (RuBP) by the enzyme Rubisco. Glycolate is then transported out of the chloroplasts and enters the peroxisome.

Inside the peroxisome, glycolate undergoes a series of enzymatic reactions known as the glycolate pathway or photorespiratory pathway. These reactions lead to the conversion of glycolate into glycine and serine, ultimately releasing carbon dioxide. The peroxisome plays a crucial role in these reactions, where the metabolite glycolate is initially transported from the mitochondria to the peroxisome for further processing.

Hence, the correct answer is option 2.
