Answer:
The digestion of carbohydrate begins in the mouth when an enzyme called amylase acts on the starch and breaks down it into the maltose (disaccharide).
After this bolus moves from the mouth to the oesophagus and then to stomach, no digestion of carbohydrate proceeds. When the bolus reaches the stomach, the acidic environment of the stomach stops the action of the enzyme amylase.
The chyme then enters the duodenum where the secretions of the pancreas contain the enzyme amylase which gins begin the digestion of the carbohydrate and thus digestion of carbohydrate is complete.
