Answer 1

If you add saliva to the mixture of the food it breaks down only carbohydrates.

• Saliva contains the enzyme salivary amylase that breaks down starch present in food.

Therefore, it helps in the digestion of carbohydrates.

• It brings about the hydrolysis of polysaccharides into disaccharides.

• Further, digestion of carbohydrates takes place in the small intestine.
