Investigation into one of the Factors that Affects the Rate of Enzyme Action Plan What is an enzyme? Enzymes are proteins that act as catalysts. A Catalyst is a chemical substance which speeds up the rate of reactions, but doesn't get used in the reaction itself. This is why catalysts are useful; they can be used many times over. The diagram below explains how enzymes break down food molecules: This diagram is known as the 'Lock and Key' diagram. This is because the food molecules fit perfectly into the enzyme, just like a key fits into a lock. Aim To see what affect increasing the enzyme Catalase has on oxygen production when the Catalase reacts with Hydrogen Peroxide (H2O2) Prediction I predict that as the concentration of the enzyme increases (i.e. more of the enzyme) then the amount of oxygen produced will increase too. I say this because the more enzyme molecules produced by a cell, the faster the...
