however‚ without enzymes‚ these reactions could possibly take several years to complete. An enzyme is a macromolecule‚ generally a protein‚ that lowers the activation energy of a reaction without being changed by the reaction‚ and this causes the reaction to occur much faster than usual (Campbell et al.‚ 2014). The act of speeding of a chemical reaction is called catalysis‚ and molecules that perform this are called catalyst. Enzymes act as catalysts‚ and there a many types of enzymes that perform many

Colleen Doyle Lab report 4 Gender Roles John Tucker Must Die John Tucker Must Die is a movie about the classic stereotypical male athlete in high school. John Tucker is the star basketball player who is sexy‚ talented and good with his words. Every girl in high school wants to date John Tucker. With his reputation‚ John dates 3 girls at once. He dates such stereotypical girls including the cheerleader‚ the “slut”‚ and the smarty-pants. Because of his name‚ he gets away this. But‚ all of this

Chirag Patel Biology 157 Determining the Effect of Varying Substrate Concentration Question: How does concentration of potatoes affect the amount of oxygen produced with hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The

Enzyme Catalysis Introduction: Enzymes are produced by living organisms as proteins. These enzymes perform as catalysts to bring about a chemical reaction. In fact‚ most reactions are catalyzed by enzymes during reactions in the cell or in the human body. A catalyst that enzymes pose ad are by definition substances that are capable of initiating or speeding up a chemical reaction. Catalyst are not a necessity during a chemical reaction‚ they are just used to speed up a chemical reaction. This event

THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a little activity would

Enzymes INTRODUCTION Enzymes are protein cells and they are found in the gut. They help to break down the food you eat. Enzymes are produced by living cells and they speed up reactions because they are biological catalysts. If we did not have enzymes‚ the reactions in our cells would be too slow to keep us alive. This means that they are extremely important for our survival. The properties of enzymes are: ⋆ They can be used many times‚ because they can speed up reactions without
