Question

In humans, protein digestion is completed in the mouth.

• A. True
• B. False

Answer 1

The correct option is B False

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. The pancreas produces a juice containing several enzymes that break down carbohydrates, fats, and proteins in food. Hence, partial digestion occurs in the mouth.
