Answer 2

Starch is broken down into sugars by the action of saliva (Option a)

• Bile juice is involved in the breaking down of fat globules and not starch.
• Hydrochloric acid will destroy starch if it enters the stomach.
• Starch is broken down by the digestive enzyme, amylase.
• It is the salivary glands that produce this enzyme.
• Thus, the breaking down of starch takes place in the mouth by the action of saliva.
