Which enzyme begins the digestion process in the mouth with the aid of saliva?

• A. Amylase
• B. Lipase
• C. Pepsin
• D. Protease

Answer: (A)

Amylase is the enzyme responsible for initiating the digestion process in the mouth alongside saliva. It specifically catalyzes the breakdown of starches into simpler sugars, such as maltose. Saliva contains amylase, which begins the process of carbohydrate digestion even before food reaches the stomach. This is an essential function as it allows for the efficient conversion of complex carbohydrates into simpler forms that can be more readily absorbed and processed by the body later in the digestive tract. The other enzymes mentioned play different roles; lipase is involved in fat digestion but primarily acts in the stomach and small intestine, pepsin predominantly starts protein digestion in the acidic environment of the stomach, and protease also refers generally to enzymes that break down proteins. Thus, amylase is specifically significant for the initial digestion of carbohydrates right in the mouth.
