Question

If the saliva is lacking in salivary amylase, then which of the following processes taking place in the buccal cavity will be affected?

Options

• proteins breaking down into amino acids

• starch breaking down into sugars

• fats breaking down into fatty acids and glycerol

• intestinal layer breaking down leading to ulcers

Answer 1

starch breaking down into sugars

Explanation:

Salivary amylase (also known as ptyalin) is a specific digestive enzyme produced by the salivary glands in the mouth (buccal cavity). Its sole function is to initiate chemical digestion by breaking down complex, insoluble starches (carbohydrates) into simpler, soluble sugars like maltose. If saliva lacks this enzyme, the chemical breakdown of carbohydrates cannot begin in the mouth.
