Answer:
a. Salivary amylase
b. Mouth
c. Stomach
d. S cells of the small intestinal crypts of Lieberkhün
Explanation:
Carbohydrate digestion begins with salivary amylase in the mouth.
This enzyme hydrolyzes to produce maltose, oligosaccharides, and glucose for around 1–2 hours before it is deactivated in the stomach. When chyme reaches the duodenum, the S cells of the small intestinal crypts of Lieberkhün is stimulated to produce even larger quantities of this enzyme to continue digestion.
