The correct response is:
**The pH of the stomach is lower than in the mouth.**
Salivary amylase works optimally at a neutral pH, which is found in the mouth. However, when food enters the stomach, it is exposed to a highly acidic environment, which denatures the salivary amylase enzyme, dramatically reducing its ability to digest carbohydrates.
