Biology · Secondary 3 · Hard · Effect of temperature and pH on enzymes
A student adds an enzyme to apple pulp at pH 3 and pH 7. Much more juice is produced at pH 5 in another trial. Why is less juice produced at pH 3 and pH 7?
- The enzyme concentration is higher at pH 5.
- The enzyme is denatured at pH 3 and pH 7.
- The substrate concentration is zero at pH 3 and pH 7.
- Osmosis only occurs at pH 5.
