Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
Enzymes and its examples:-
1) Amylase - Helps change starches into sugars.
2) Maltase - Also found in saliva breaks the sugar maltose into glucose.
3) Trypsin - Found in the small intestine, breaks proteins down into amino acids.
