An investigation into the rate of reaction of the enzyme urease Introduction Enzymes are protein molecules produced in living cells. They act as biological catalysts. They are specific to certain reactions, and so they only operate within narrow temperature and pH ranges. Urease is an enzyme that breaks the carbon-nitrogen bond of urea to form ammonia and carbon dioxide. This can be represented in the equation: Urea urease ammonia + carbon dioxide (NH2)2CO urease NH3 + CO2 The rate of reaction of the enzyme can be affected by the following variables: a) pH: at too high pH, the enzyme is denatured due to the loss of H+ ions. The same applies for too low a pH level, where too many H+ ions would attach to the negative regions of the enzyme, changes its shape and causing it to denature. b) Concentration of enzyme: The higher the concentration, the higher the rate of reaction will be. With a...
