Hydrogen Peroxide Reaction With Catalase

Hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell.

Hydrogen peroxide reaction with catalase. Living cells produce an enzyme called catalase that quickens the breakdown of a damaging substance called hydrogen peroxide. The catalase enzyme is found inside cells of most plants and animals. This investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies. Nearly all living things possess catalase including us.

Invert it over the trough of water with the open end under the surface of the water in the bowl and with the end of the rubber tubing in the measuring cylinder. To maintain hydrogen peroxide levels the catalase enzyme deconstructs hydrogen peroxide and reconstructs the reactants into oxygen gas and water. This enzyme like many others aids in the decomposition of one substance into another. Measure 2 cm3 of hydrogen peroxide into the 2 cm3 syringe.

Enzyme lab report hydrogen peroxide is a toxic byproduct of cellular functions. Hydrogen peroxide is the by product of respiration. The reaction is speeded up by the presence of enzyme namely catalase which is used in this experiment. This is needed for organisms as the reaction rate of the decomposition of hydrogen peroxide is too slow to protect cells against the oxidation of hydrogen peroxide.

Catalase acts as the catalyzing enzyme in the decomposition of hydrogen peroxide. This mechanism is important in living organisms skin cells and body system particularly in man. Hydrogen peroxide is a byproduct of many metabolic reactions including the oxidation of fatty acids in the peroxisome of cells. The chemical formula for the decomposition of hydrogen peroxide is 2 h2o2 2 h2o o2.

Abstract catalase is an enzyme needed to break down hazardous hydrogen peroxide into nonhazardous oxygen and water. Fill the 50 cm3 measuring cylinder with water. The following word equation summarises this reaction. The effect is speeded up by the occurrence of enzyme specifically catalase which is employed in this test.

As an oxidizer it will decompose to form oxygen and water. Catalase is an important enzyme that breaks down hydrogen peroxide h2o2 into water and gaseous oxygen both of which are relatively harmless to cells. Hydrogen peroxide h2o2 is a by product of respiration and is made in all living cells.
