How and why do enzymes work?

Enzymes ar biological catalysts. They increase the speed of a chemical reaction, without being affected or altered themselves. Our bodies contain hundreds of enzymes, each catalysing a particular reaction (increasing the reactions speed), by reducing the amount of pushing required to activate the reacting molecules - the activation energy.

Enzymes ar very important, and if they were non present, life as we know it would be possible. The core temperature of a healthy human body is only 37oC, and without catalysts, most of the reactions inwardly the cells of the body would be much too slow to earmark life to go on. Only with the addition of enzymes advise we die hard certain foods and clean our systems. Even though there are many distinct enzymes, only one kind of enzyme can react with a different substance

If either particle doesnt match, a reaction cannot occur. The particles that an enzyme works on are called the substrate. Each enzyme has a small area on its surface, which is called the active site. The substrate fits into the identical active site on only one attribute of enzyme. A reaction will then occur and different products are formed.



When the substrate joins with the active site, it lowers the energy required for the reaction to take place, allowing the products to be formed more easily

Notice that after the reaction has occurred, the enzyme is free to act on more substrate molecules.

Most enzymes give way evolved to work most efficiently at around 37oC. This is the crusade for catalase. This should be an important factor to be considered in our experiment.

However enzymes are constructed from proteins, which denature from 40oC. Once an enzyme has denatured it becomes useless. This is much the same as cooking an egg. The egg is made of protein, and...
