work of an enzyme
This is to show what occurs to the food that we consume on a daily basis.One of the process that bring growth in mammals (human beings) is the intake of diffrent types of food. And this food that we eat cannot generate growth by itself but it has to work with glands, hormones, enzymes etc. With this report we will focus on how enzymes reacts with the food or whatever we take in.

What is an enzyme? An enzymes is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. It is a biochemical catalyst that allow chemical reaction to take place, it is a functional protein that regulates various metabolic pathway of the body.

On this note what is a catalyst? A catalyst is a chemical that reduces the amount of activation energy needed to start a chemical reaction. Catalyst participate in chemical reaction but are not themselves changed by the reaction.

The Objective : The role of an enzyme in the cell is to act as a chemical catalyst that allow metabolic reaction. Enzymes are proteins and have the chemical properties of proteins.They are usually tertiary or quaternary proteins of complex shape . Often their molecule contain a cofactor inorganic iron or vitamins may make up part of a cofactor if the cofactor is an organic non protein molecule it is called coenzyme.

...“globules” in the small intestine. In this form it is nearly impossible for the enzyme pancreatic lipase to catalyse the breakdown of lipase into monoglycerides and free fatty acid because it has only a small surface area on which area to work pancreatic lipase. The first step in lipase digestion is to breakup this large fat globule into smaller piece, a process called emulsification.

Protein digestion begins in the stomach with the enzyme pepsin secreted from chief cells in the gastric glands as the inactive proenzyme pepsinogen becomes the active enzyme pepsin when it encounters an acidic environment pepsin begins digestive proteins into polypeptides and free amino acids . The remainder of protein digestion occur in the small intestine with pancreatic enzymes such as trypsin and kimotripses and also brush border enzyme such as carboxy peptides and amino peptides.

Altering the Amount of Heat Produced When Magnesium Reacts with Sulphuric Acid

- Altering the Amount of Heat Produced When Magnesium Reacts with Sulphuric Acid When energy in the form of heat is given out of a reaction it is an exothermic reaction. Exothermic reactions usually need activation energy, the energy to break the bonds in the chemicals and to start the reaction. Once the bonds are broken new stronger bonds are formed. In an exothermic reaction energy in the form so heat is given out to the surrounding when the products are formed. Therefore there is an average rise in temperature; energy is lost which results in a negative ?H....   [tags: Papers]

Chemical Kinetics: Enzymes Essay

- Chemical Kinetics is the branch of chemistry that studies the speed at which a chemical reaction occur and the factor that influence this speed. What is meant by the speed of a reaction is the rate at which the concentrations of reactants and products change within a time period. Some reactions occur almost instantaneously, while others take days or years. Chemical kinetics understanding I used in the process of designing drugs, controlling pollution and the processing of food. Most of the time chemical kinetics is used to speed or to increase the rate of a reaction rather than to maximize the amount of product....   [tags: Chemical Kinetics: Enzymes]

Real Life Uses for Metabolic and Digestive Enzymes Essay

- Enzymes are protein based molecules that help to speed up reactions in other molecules. They cause reactions without being used up or changing after the reaction is completed. Enzymes are the body’s workers and they are produced by all living things. Enzymes are made of chains of amino acids. The amino acids are linked in specific ways to complete whichever job they were made to do. Each enzyme was built for a different job and will only work with a specific substance. The efficiency of enzymes is dependant on the temperatures that enzymes are exposed to....   [tags: metabolic enzymes, digestive enzymes, biology,]

Enzyme And The Enzyme Of Enzymes Essays

- Enzymes are protein molecules that are made by organisms to catalyze reactions. Typically, enzymes speeds up the rate of the reaction within cells. Enzymes are primarily important to living organisms because it helps with metabolism and the digestive system. For example, enzymes can break larger molecules into smaller molecules to help the body absorb the smaller pieces faster. In addition, some enzyme molecules bind molecules together. However, the initial purpose of the enzyme is to speed up reactions for a certain reason because they are “highly selective catalysts” (Castro J....   [tags: Enzyme, PH, Enzyme substrate, Chemistry]

Essay on Enzymes

- Enzymes Enzymes are biological catalysts. A catalyst is defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanentchange. Enzymes do precisely this in living things. Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Enzymes have two main functions: To act as highly specific catalysts, and also to provide a way of controlling reactions, the amount of enzyme determines how quickly the reaction can proceed....   [tags: Papers]

Enzymes Essay

- Enzymes are presented in many different shapes and sizes because form fits function. Enzymes play an active role in everyday life, in every living organism. What all enzymes have in common is that they are proteins meant to speed up chemical reactions because without them reactions would occur at an extremely slow rate. This would be a conflict for every living thing which is why enzymes are so important. Enzymes are defined as “a protein formed by the body that acts as a catalyst to cause a certain desired reaction” (1)....   [tags: Scientific Research ]
