Catalase is an enzyme which decomposes hydrogen peroxide into water and oxygen. Catalase was introduced into a hydrogen peroxide solution, and the oxygen given off was gathered in a gas syringe. The overall volume of oxygen produced from the beginning of the reaction was measured every 10 seconds for 1 minute. The results are displayed in the table. What conclusion can be drawn from these results?
- AThe reaction stopped after 60 seconds and no more oxygen was produced.
- BThe highest rate of oxygen production occurred 10 seconds after the start of the reaction.
- CIt took more than 20 seconds from the start of the reaction for half of the substrate to be converted to water and oxygen.
- DThe mean rate of reaction between 20 and 30 seconds was twice the mean rate of reaction between 30 and 40 seconds.
