Biology · Secondary 4 · Medium · Effect of temperature and pH on enzymes
A student investigates the effect of pH on amylase activity using starch solution. At pH 7, all starch is digested in 4 minutes. At pH 3, some starch remains after 10 minutes. What is the most likely explanation?
- Starch molecules move slower at pH 3.
- Amylase is denatured or less active at pH 3.
- Starch cannot dissolve at pH 3.
- Amylase concentration is higher at pH 3.
