Which 3 factors affect the rate of an enzyme reaction ...

An increase in temperature beyond the optimum causes the enzyme’s active site to become denatured . Some enzymes (e.g. in biological washing powders) are thermostable, meaning they can work at a wide range of temperatures. This allows biological washing powder to be used at low temperatures that saves energy and money.

O level biology Notes: Enzymes

Mar 01, 2015·Enzymes. Enzymes are proteins that function as a biological catalyst. They are proteins in nature. A catalyst is a substance that speeds up a chemical reaction but isn’t changed by the reaction. Hydrogen peroxide (H2O2) is a substance that decomposes into Water (H2O) and Oxygen (O2) if it is left in room temperature for a period of time.
