It is false that the digestion of polypeptides begins in the mouth with the enzyme pepsin.
<u>Explanation:</u>
The food is consumed through the mouth. Here the saliva has an enzyme called amylase which helps in the breaking down of foods to simpler substances. The food is sent through the oesophagus to the stomach.
In the stomach pepsin breaks down proteins into polypeptides. In stomach is where the enzyme pepsin is found. Then the bile juice secreted in the liver acts upon the digested food and then in the small intestine. Then the feces are excreted through the anus.
