ABDULLAH QANDEEL INTRODUCTION In this experiment I will be investigating and analyzing the factors affecting the rate of decomposition of hydrogen peroxide by catalyse in immobilised yeast. This essentially an enzyme practical. You know that various things alter the rate of enzyme-controlled reactions. I plan to carry out an experiment that investigates how one factor alters the following reaction: Hydrogen peroxide (2H2O2) Catalyse Enzyme Water (2H2O) + Oxygen (O2) Enzymes are biological catalysts that speed up reactions in living organisms. Without them reactions would be too slow for organisms to survive. Hydrogen peroxide is a waste product formed in cells. Since it is a highly poisonous (a powerful oxidising agent), it must be broken down as quickly as possible. Catalyse is an enzyme found in all cells that breaks down hydrogen peroxide to water and oxygen (harmless products). It is a very fast enzyme (the fastest known today) As catalyse is found in yeast, a...
