Answer:
All organisms are made of four types of carbon-based molecules: carbohydrates, lipids, proteins, and nucleic acids.
Enzymes are mainly protein molecules in cells which work as biological catalysts. Enzymes speed up chemical reactions in the body, but do not get used up in the process, therefore can be used over and over again. With an enzyme, chemical reactions go much faster than they would without the enzyme.
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.
Different types of enzymes can break down different nutrients:
amylase and other carbohydrase enzymes break down starch into sugar.
protease enzymes break down proteins into amino acids.
lipase enzymes break down lipids (fats and oils) into fatty acids and glycerol.
