The Affect of Enzyme Catalase on the Rate of Decomposition of Hydrogen Peroxide
An experiment was conducted in order to identify the effect of enzymes on the rate of a reaction. The experiment was divided into two sections. In one part, the rate of decomposition of H2O2 under normal environment....
atkins diet
Today local reporter Lindsay Lehrer will tell us how dangerous high protein low carbohydrate diets are for your body and cells. First a little background information; the four major macromolecules of life are nucleic acids, proteins, lipids, and carbohydrates. Now back to the real surprising story. ....
Biological washing powders
BIOLOGICAL WASHING POWDERS
Introduction:
Enzymes have been around for quite a while now. They have a wide range of applications and they range from them being used in hospitals to remove blood stains and kill bacteria on the tools used, to our very own house where they are used in washing powd....

Enzymes
The basic mechanism by which enzymes catalyse chemical reactions begins with the binding of the substrate to the active site on the enzyme. The active site is the specific region of the enzyme which combines with the substrate. The binding of the substrate to the enzyme causes chan....
effect of different substrate concentrations on the rate of reaction of catalase.
Aim:
The aim of my investigation is to find out how the substrate concentration, hydrogen peroxide affects the rate of reaction of the enzyme catalase. I will do this by reacting different concentrations of hydrogen peroxide with the same volume of catalase (yeast mixed with water) and then obs....
Enzymes
There are many things that can affect the rate of enzyme reactions. Enzymes being organic catalysts, catalysts are substances used to speed up chemical reactions. The affect of pH on the rate of an enzyme reaction is said that a change in pH can alter the R groups of the amino acids. This will cause....

ENZYME INVESTIGATION
Planning
Introduction: An Enzyme is any one of many specialised organic substances, composed of polymers of amino acids, that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms. Those enzymes identified now numb....
Extracting DNA from the Bacterium Escherichia Coli
Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmissionpossible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable thenext generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each"....

Investigating Enzymes
The effect of enzyme concentration, on enzyme activity.
Aim: To explain how changing the concentration of an enzyme affects the enzymes activity. We are using apple as the substrate, which determined why we used pectinase as the enzyme. Pectinase is a general term for enz....
Pancreas
Name and FunctionsThe part I researched, which has only one name, is the pancreas. The pancreas is an organ that produces digestive juices necessary to break down food. It also produces insulin and glucagons. Insulin and glucagons are two hormones needed to break down sugar and to regulate our metab....
Proteins
Proteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word proteies or primary. Proteins have many different prop....
Proteins
Proteins are molecules made-up of one or more chains of amino acids joined by peptide bonds. Enzymes are important proteins that guide almost all chemical reactions that occur inside cells. Most cells contain hundreds of different enzymes because each enzyme assists only one or a few specific reac....
