Effect of temperature and pH on enzymes
Biology · Secondary 4 · Medium · Effect of temperature and pH on enzymes
An enzyme that works in the human stomach has an optimum pH of 2. A student adds this enzyme to a solution at pH 8.
What is the most likely effect on the enzyme’s activity?
What is the most likely effect on the enzyme’s activity?
- Its activity will decrease greatly because the pH is far from its optimum.
- Its activity will increase because all enzymes work best in alkaline conditions.
- Its activity will stay the same because pH does not affect enzymes.
- It will be converted into a different enzyme that works at pH 8.
