Investigating the break down of Hydrogen Peroxide using catalyst PLAN: Aim: To investigate the rate at which hydrogen peroxide is broken down by the enzyme catalyst by measuring the volume of oxygen produced. Variables: Catalyst is an enzyme that breaks down hydrogen peroxide into water and oxygen. The factors that affect the activity of catalyst are: · Hydrogen peroxide concentration · Substrate concentration · Temperature · PH The variable chosen to investigate is the concentration of the substrate Hydrogen Peroxide. The other variables will have to remain the same to ensure that it is a fair test. Scientific knowledge: Enzymes Enzymes are biological catalysts; they speed up the rate of a chemical reaction whilst remaining chemically unchanged them. Enzymes are among the most powerful catalysts, and play an essential role in living organisms, where they accelerate reactions that would otherwise require temperatures that would destroy most of the organic matter. Enzymes are made of proteins,...
