Enzymes are part of the chemical digestion process. Their function is to break down the macromolecules. Amylase is a digestive enzyme secreted in the mouth and pancreas and is responsible for breaking down of starch.

Explanation:

Enzymes acts as catalysts, increases the rate and activates the chemical reactions during digestion process.

These biochemical reactions break down the macromolecules present in the undigested food into smaller molecules in the form of glucose and produces energy molecules in the form of ATP molecules.

Amylase is the digestive enzyme secreted by the salivary glands in the mouth. It is also produced in the pancreas. Amylase is mainly involved in breaking down of complex starch molecules in the food into simpler monosaccharides.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
