Effect of temperature and pH on enzymes
Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
In an experiment, catalase and hydrogen peroxide are mixed at 25 °C. The reaction is then repeated at 60 °C with all other conditions unchanged. The froth formed at 60 °C is much lower. Why?
- The enzyme is denatured and works more slowly
- The hydrogen peroxide freezes at 60 °C
- The enzyme concentration becomes higher
- The pH of the solution becomes neutral
