Catalysts speed up the rate of the reaction. lowers the energy input required for a chemical reaction to happen remains unchanged at the end of the reaction When you think of a catalyst think of a fire! Enzymes Enzymes are Biological catalysts https://www.youtube.com/watch?v=XTUm-75-PL4 Enzymes control chemical reactions that take place in the cytoplasm. Catalase in an example of an enzyme made by living cells Catalase The enzyme catalase breaks down the waste substance hydrogen peroxide into water and oxygen. H 2O 2 catalase (substrate) (enzyme) oxygen +water (products) Degradation reactions animation Synthesis Reaction es Active site Degradation reactions Starch Maltose Enzyme activity Temperature and pH affect the activity of an enzyme. Optimum Condition Enzymes function best or are most active in specific conditions known as optimum conditions. Degradation reaction Substrate Enzyme Product Hydrogen peroxide Starch Catalase Amylase Oxygen and water Maltose Maltose Maltase Glucose Protein Pepsin Peptides Peptides Protease Amino acids Fats Lipase Fatty Acids and Glycerol Used for: Waste product Synthesis reaction Glucose-1phosphate Starch Properties of enzymes 1. Speed up reactions. 2. Made of protein. 3. Are specific. 4. Not used up during the reaction. 5. Require optimum conditions at which best. they work 6. At high temperature they become denatured (they break down) Lock and Key https://www.youtube.com/watch?v=myOR DWVzNhc
