Hint:
Starch is digested in the mouth, stomach and small intestine. Enzyme responsible for starch digestion is carbohydrase enzyme and amylase. These enzymes are present in saliva. If we start chewing any food material then it will break down to sugar and it begins to taste sweat.
Complete answer:
Digestion is the mechanical and chemical breakdown of food in small organic fragments. Different organs play roles in the process of digestion. The living creatures need carbohydrates, protein and fats.
Digestion of starch begins in the mouth when we start mechanical digestion by chewing the food. We breakdown food in small sized particles so that chemical digestion takes place Easily. Chemical digestion starts from the mouth itself, due to presence of salivary glands in the mouth which secrete saliva, and saliva contains many enzymes like amylase enzyme, which begins the breaking down of starch.
So, option A is Stomach – Stomach is not the part of the mouth and food goes down in the stomach after the mouth. And in question, it is asked that from where digestion starts actually, so, option A, is not the correct answer.
Option B, is Intestine – Intestine is the last organ of the digestive system. So, Option B, is not our answer for this question.
Option C, is Oesophagus – Oesophagus is the muscular tube that connects the mouth to the stomach. So, it comes after the mouth. So, option C is also not the correct answer.
Option D, is Buccal cavity – Buccal cavity which is also known as oral cavity present in the mouth.
Thus, the correct answer is option D, that is, Buccal Cavity.
Note:
Digestion of starch also takes place in other organs of the digestive system like intestines, but digestion of starch starts from the mouth due to saliva.
