Question

Quizplus · Accepted Answer

Superoxide dismutase enzyme catalysis is faster than the rate of diffusion because it has an electric field around the active site. This electric field helps to attract and orient the substrates, making the reaction more efficient. Additionally, the active site of the enzyme is specific for the substrate, which also increases the rate of the reaction. Acid-base catalysts and two-step reactions may also increase the rate of the reaction, but they are not specific to superoxide dismutase catalysis. The fact that superoxide dismutase occurs in high quantities in cells does not affect the rate of the reaction compared to diffusion.
