Where does the digestion of starch begin?
A
esophagus
B
small intestine
C
stomach
D
mouth
Explanation: 

Detailed explanation-1: -The digestion of starch starts in the mouth. Salivary amylase present in the saliva breaks down carbohydrates like starch into simpler units called maltose.

Detailed explanation-2: -Starch digestion begins in the mouth with the addition of salivary amylase to food particles. Salivary amylase acts specifically on starch in the food and breaks them down to more simple compounds such as maltose.

Detailed explanation-3: -Salivary amylase works to break the starch molecules into their smaller disaccharide building blocks, such as maltose. Once we swallow our food, it enters our stomach, where strong gastric juices will continue the digestive process. Digestion is completed in the small intestine.

Detailed explanation-4: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.

Detailed explanation-5: -Amylase coats and surrounds each starch molecule in your mouth. Then the enzyme deconstructs complex starch molecules through hydrolysis, or chemical breakdown, turning them into smaller, more manageable particles.
