  1. Introduction to ENZYMES

  2. Why are enzymes important? • Enzymes are catalysts of biochemical reactions. (speed up reactions) • Enzymes are small biochemical digesters. They have the individual power to break apart vitamins, minerals, proteins, carbohydrates, fats and make them absorbable in our bodies  • All activity of life depends on them. 

  3. Properties of an enzyme • Enzymes are made of proteins. • Only a small amount is needed change the speed of reactions. • They remain unchanged at the end of the reaction. They are "reusable". • They are highly specific. • Each enzyme can only work on one chemical reaction. Example, catalase will only work on hydrogen peroxide (to form water and oxygen). • They are affected by temperature. • They are affected by pH. • What happens to enzyme under extreme conditions?
