Question
The decreased carbon dioxide fixation in some C3 plants is because of:
- Oxygen binding to RuBP
- Oxygen binding to RuBisCO
- Unavailability of RuBP
- Phosphoglycolate formation
Hint:
Carbon fixation is the process by which plants fix atmospheric carbon to form organic compounds.
The correct answer is: Oxygen binding to RuBisCO
The decreased carbon dioxide fixation in some C3 plants is because of: Oxygen binding to RuBisCO
The active site of RuBisCO can bind to both oxygen and carbon dioxide. when oxygen binds to RuBisCO, carbon dioxide fixation is reduced as the active site of RuBisCO is not able to carbon dioxide.
