Binding of oxygen to RuBisCo A)destroys enzymatic function because oxygen is a suicide inhibitor of the enzyme. B)targets the enzyme for proteolytic degradation. C)decreases the enzyme's K_m for oxygen since binding is cooperative. D)activates the enzyme for carbon fixing reactions. E)costs the cell ATP since energy is required to replace intermediates necessary for carbon fixation.

Question

Quizplus · Accepted Answer

Binding of oxygen to RuBisCo leads to photorespiration, which consumes ATP and reduces the efficiency of photosynthesis by using energy to replace intermediates necessary for carbon fixation.
