If salivary glands do not work properly, which digestion will be affected first?
Answer and explanation
Correct answer: Digestion of starch
The governing concept is the location and function of the first digestive enzymes. Salivary glands release saliva into the mouth, and saliva contains salivary amylase, which begins the digestion of starch before food reaches the stomach. If these glands malfunction, this initial starch digestion is directly affected first. Thus option B is correct. Most fat digestion occurs later with bile and lipase, major protein digestion begins in the stomach, and water is absorbed rather than digested.
