Catalase breaks down hydrogen peroxide about107times faster than the uncatalyzed reaction. If the latter required one year, how much time would be needed by the catalasecatalyzed reaction?
Mechanisms of catalysis: 2.5 Mechanism of chymotrypsin summary. These mechanisms involve several of the above-mentioned catalyses. In these summaries, do not just draw a diagram of the proposed mechanisms. It is more important to understand which reaction steps involve what kind of catalysis and how these help to reduce the activation energy needed for the reaction (e.g. a step in the reaction mechanism could be electrostatic catalysis to stabilise the transitions state)
