Question : Inhibition of photosynthesis in the presence of O2 in C3 plants is called
Option 1: Hexose monophosphate shunt
Option 2: Pasteur effect
Option 3: Decker effect
Option 4: Warburg effect
Correct Answer: Warburg effect
Solution : The correct option is the Warburg effect.
Photorespiration is the slowing of photosynthesis caused by high oxygen concentrations and it is also known as the "Warburg Effect." When the oxygen concentration in the leaf exceeds the carbon dioxide concentration, the oxygen molecule binds to the enzyme ribulose-1, 5-bisphosphate carboxylase/oxygenase (RuBisCO) instead of carbon dioxide. This procedure is energy inefficient and lowers photosynthesis efficiency.
