Biology:Warburg effect (plant physiology)

From HandWiki
Short description: Biological phenomenon

In plant physiology, the Warburg effect is the decrease in the rate of photosynthesis due to high oxygen concentrations.[1][2] Oxygen is a competitive inhibitor of carbon dioxide fixation by RuBisCO which initiates photosynthesis. Furthermore, oxygen stimulates photorespiration which reduces photosynthetic output. These two mechanisms working together are responsible for the Warburg effect.[3]
