Question

A process that makes important difference between $C_3$ and $C_4$ plants is

• A. Glycolysis
• B. Calvin cycle
• C. Photorespiration
• D. Respiration

Answer 1

Answer: (C)

Photorespiration is the light dependent process of oxygenation of ribulose biphosphate and release of carbon dioxide by the photosynthetic organs of a plant. It occurs in chloroplast. Peroxisome and mitochondria are required for completing the process. This process creates an important difference between $C_3$ and $C_4$ plants as it is absent in $C_4$ plants.
