Question

2 — digestion and absorption of carbohydrates
learning objective: determine how carbohydrates are digested and absorbed.
where does the digestion of carbohydrate molecules begin?
a.) stomach
b.) small intestine
c.) esophagus
d.) mouth

Explanation:

Carbohydrate digestion begins in the mouth. Saliva contains salivary amylase, an enzyme that starts breaking down starches (a type of carbohydrate) into smaller sugar molecules. The stomach primarily digests proteins, the esophagus is a transport tube with no digestive enzymes for carbs, and the small intestine continues carbohydrate digestion but doesn't start it.

Answer:

d.) Mouth
