Effect of temperature and pH on enzymes
Biology · Secondary 4 · Medium · Effect of temperature and pH on enzymes
A student investigates the effect of pH on an enzyme that works in the small intestine. The enzyme works best at pH 8. Which prediction about its activity at pH 3 is most likely correct?
- Its activity will be very low because the enzyme is denatured at pH 3
- Its activity will be highest because pH 3 is more acidic
- Its activity will be unchanged because pH does not affect enzymes
- Its activity will be slightly higher than at pH 8
