Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

Trade-Offs and the Bullwhip Effect A trade-off refers to any situation that entails losing an aspect or quality of an item in return for achieving another aspect. In the corporate context‚ the term is majorly used in cases where there is the need to get rid of some things in return for other better things (Khayum‚ 2003). There are a number of trade-offs that impact the operations of business organizations. Inventory Transportation Costs Inventory transportation costs refer to the costs of delivering

to the full moon. Maybe not so much today‚ but a long time ago‚ a lot of stuff got blamed on the moon. Although a majority of people no longer blame the big bad moon‚ some people believe that the moon has an affect on us. This is called the Lunar Effect. Actually several studies have been done to see if the moon really affects humans and animal. A study was done at the Colorado State University Veterinary Medical Center and the study showed that during the full moon more pets have come in. It showed

Introduction:The purpose of this lab was to determine the activating effect of aniline‚ phenol‚ anisole and acetanilide after reacting with pyridinum tribromide in order to undergo electrophilic aromatic substitution. The melting point of the isolated products were measured against the standards in order to determine how strong of an ortho/para activator the compound was based on the product(s) and melting point obtained. Theory: Electrophilic aromatic substitution is an organic reaction that takes

The Joule-Kelvin effect - the expansion of a real gas This famous experiment performed in 1852 was a follow-up to those of Gay-Lussac (1807) and Joule (1845) and demonstrated that there were indeed attractive forces acting between gas molecules. In theory‚ if attractive forces do exist then when a gas expands its temperature should drop. The potential energy of the gas molecules has been increased and therefore in an isolated system its kinetic energy‚ and thus its temperature‚ should fall.

Bad Effects of Smoking http://www.articledoctor.com/quit-smoking/bad-effects-of-smoking-2331 Cigarette smoking is usually associated with breathing trouble and lung cancer. But smokers are at a high risk of developing several chronic disorders. Along with high blood pressure‚ high cholesterol‚ obesity and diabetes‚ smoking is a major independent risk factor for a coronary heart disease or kidney failure. It causes damage by decreasing the oxygen flow to the heart. It increases the blood pressure

The Effect of Divorce 50 percent of children in the United States watch their parents go through a divorce (Children-and-divorce.com). If you have 10 friends‚ 5 of those friends could have divorced parents. Do you know how it feels to have divorced parents? Maybe you do know‚ maybe you are a victim of divorce. Even though it might be for the best of the parents‚ the loss of stability that comes from a divorce affects children and even adults in many ways. Many children who suffer through their parents

weapon. The destructive power in fusion weapons comes from the combining of very light atoms‚ such as hydrogen. The atoms of the element are fused‚ and they release a great amount of energy. The element must first be heated to a temperature of 50 million degrees Celsius. The only way to do this‚ without using more energy than is produced‚ is to use a fission explosion. So‚ a ball of hydrogen is surrounded by either uranium or plutonium and then by a non-nuclear explosive. The explosive is set off

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded
