Enzymes catalyze biochemical reactions and their initial velocity can be measured. Malonate is a competitive inhibitor of the enzyme succinate dehydrogenase, which means it competes with the normal substrate succinate for the enzyme's active site, preventing the enzyme from binding and acting on succinate.
