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

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

Varibles that affect Enzyme Catalysis Reaction Rates Introduction Molecules are constantly moving in our bodies and in nature. When molecules move fast enough they collide into one another‚ allowing chemical reactions to occur. Factors such as temperature and concentrations can either help increase or decrease these reactions. (Jubenville.) Enzymes are known as catalyst because they are able to speed up reaction rates without being destroyed or altered. They are able to encourage chemical reactions

There are many types of stories. Of these stories‚ there are over 900 versions of Cinderella. But in this essay‚ I will only be talking about four of them. I will compare‚ contrast‚ and conclude those four versions called‚ “Yeh-Shen”‚ “The Algonquin Cinderella”‚ “Aschenputtel”‚ and “Interview” in this essay. One thing you probably didn’t know‚ is that these three stories are very old‚ which is something they all have in common. They also all have an element of magic. For example‚ Aschenputtel had

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction
