Question

Digestion of starch takes place in

• A. Stomach and duodenum
• B. Buccal cavity and small intestine
• C. Buccal cavity and oesophagus
• D. Duodenum only

Answer 1

The correct option is B Buccal cavity and small intestine

• Carbohydrate digestion begins in the mouth. The salivary glands in the mouth secrete saliva, which helps to moisten the food.
• The food is then chewed while the salivary glands also release the enzyme salivary amylase, which begins the process of breaking down the polysaccharides in the carbohydrate food.
• But this activity is much less important than that of pancreatic amylase in the small intestine which digests carbohydrates. Hence, Digestion of starch takes place in the buccal cavity and small intestine.

So, the correct answer is 'buccal cavity and small intestine'.
