Effect of temperature and pH on enzymes
Biology · Secondary 4 · Medium · Effect of temperature and pH on enzymes
During digestion, the enzyme amylase breaks down starch into maltose. In an experiment, a student adds amylase to a starch solution at pH 7 and 37 °C. Which change would most likely DECREASE the rate of this enzyme reaction?
- Heating the mixture to 80 °C
- Keeping the mixture at 37 °C but adding more starch
- Cooling the mixture from 37 °C to 30 °C
- Keeping the mixture at pH 7 but adding more amylase
