TEMPERATURE'S EFFECT ON CATALASE
INTRODUCTION:
Enzymes are the organic catalysts in which living
cells utilize to speed up chemical reaction. Hydrogen
peroxide (H2O2) is a product of all organisms that use
molecular oxygen. H2O2 is damaging to cell because it
is a strong oxidizer. Cells have an enzyme that
breaks up the H2O2 into water and oxygen rapidly
called catalase. This prevents cellular damage and is
abundant in liver cells because the liver detoxifies
harmful substances that include peroxide. This
creates a layer of foam on the surface. The amount
and speed of the foam are measurements of catalase
activity. Showing the rate of breakdown of H2O2
occurs in all cells. The following experiment was
made for observation
1 ml of water + 1ml of H2O2 Measurement after 1 minute
Tube 1 - apple 2mm
Tube 2 - potato 1mm
Tube 3 - beef steak 2mm
Tube 4 - beef liver 8mm
Therefore, the liver extract does break down the H2O2
quicker.
OBJECTIVES:
In this research, we will be comparing foam
measurements in order to figure out the change...
