Catalase Enzyme Lab Samiya Hussein March 9‚ 2012 Introduction In order to receive the necessary amounts of energy required for daily function‚ the digestive system must break down proteins‚ fats and carbohydrates. In doing so‚ the body produces poisonous chemicals; however‚ the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide

The pH scale is used to measure how acidic or basic a living cell can be. The pH scale ranges from 0-14; 0-6 being acidic‚ 8-14 being basic and 7 being neutral. There are many factors

Inflationary gaps When aggregate demand exceeds an economy’s productive potential there is an inflationary gap. We tend to see rising inflation and a worsening trade situation at these times. This situation occurs when the economy has been growing for some time leading to a build up of inflationary pressure as demand rises. In the late 1980s there was a cyclical boom in the economy that led to a large inflationary gap. Consumer demand increased by over 7.5% in real terms during 1988 and the economy

the time they get to school most of these boys know how to play the game already. By playing the game of football in school it teaches boys how to play together as a team and to get along with their team mates. As football is a team sport they must learn to all focus on the same goal and that is winning. This is drilled into them from a very young age starting with the parents to the teachers and coaches. The team sport also teaches them how to be good sports when they lose as they learn from

In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

A spectrophotometer evaluated the measurement of color change over a period time due to product being formed. Determining unknown phosphatase and effects from different inhibitors were determined by varying the pH and substrate concentrations. The unknown phosphatase analyzed showed it was an acidic phosphatase. Ph 5 had

Laws change on a daily basis‚ some of them effect the old‚ yet some effect the young. Laws are set forth to govern what we do to ensure fairness‚ equality‚ and safety for others. Recently new laws have been passed which effect new drivers. These laws mainly pertain to the younger generation of driver mainly teenagers.
