what is the difference between mechanical and chemical digestion ?

Mechanical digestion :- In this type of digestion the food is broken down into simple particles in mechanical way ,

like chewing in mouth by teeth and churning of food in stomach by the muscular movements of the smooth muscles of stomach walls.

Chemical digestion :- In this type of digestion the complex molecules of food are broken down into very simple molecules by the help of specific protein molecules called enzymes.

For example the starch is converted into simple sugar in our mouth by enzyme – amylase

the protein is digested with the help of pepsin in our stomach.

And fats are broken down into simple fatty acids by the enzyme lipase.
