Inhibition of $C_{3}$-cycle by $O_{2}$

Vedclass · Answer

(A) Otto Warburg observed that high concentrations of $O_{2}$ inhibit the rate of photosynthesis in $C_{3}$ plants. This phenomenon is known as the Warburg effect.It occurs because $O_{2}$ competes with $CO_{2}$ for the active site of the enzyme RuBisCo.When $O_{2}$ binds to RuBisCo,it initiates photorespiration ($C_{2}$-cycle) instead of the Calvin cycle ($C_{3}$-cycle),thereby reducing the efficiency of photosynthesis.Therefore,the Warburg effect is the inhibition of the $C_{3}$-cycle by $O_{2}$.
