(C) The Warburg effect refers to the inhibition of the rate of photosynthesis in $C_3$ plants when the concentration of $O_2$ is high.

When $O_2$ binds to $RuBisCO$, it initiates the process of photorespiration instead of the Calvin cycle, which reduces the overall efficiency of photosynthesis.

The inhibition of photosynthesis at high concentrations of $O_2$ is known as:
