Identify the organelle which is not involved in photo- respiration:

AChloroplast

BPeroxisome

CMesosome

DMitochondria

Answer:

C. Mesosome

Read Explanation:

  • Photorespiration is a process that occurs in Calvin Cycle during plant metabolism.

  • In this process, the key enzyme RuBisCO that is responsible for the fixing of carbon dioxide reacts with oxygen rather than carbon dioxide.

  • Chloroplast, mitochondrion and peroxisome are the three cell organelles which are involved in photorespiration. Their sequence of involvement is Chloroplast-peroxisome-mitochondrion.
