Effect of temperature and pH on enzymes
Biology · Secondary 4 · Hard · Effect of temperature and pH on enzymes
An enzyme that digests protein in the stomach has an optimum pH of 2. The same enzyme is placed in a solution at pH 8 and kept at body temperature.
What will most likely happen to the rate of reaction, and why?
What will most likely happen to the rate of reaction, and why?
- It decreases because the enzyme is denatured at pH 8.
- It increases because more collisions occur at pH 8.
- It stays the same because temperature is unchanged.
- It stops only because all substrate is used up.
