Where does amylase act to digest starch?

Explanation:
Amylase works where it can be produced and where the environment lets it function. Salivary amylase in the mouth starts breaking down starch right away, so digestion begins there. It then continues in the small intestine, where pancreatic amylase is released into the gut and works at a neutral pH provided by bicarbonate. The stomach is acidic, which inactivates amylase, so starch digestion isn’t carried out there. After starch is broken into smaller sugars, other enzymes finish the job in the intestine. So, the best answer points to the mouth and the small intestine.
