The Effect of Temperature on Enzyme Activity and Oxygen Production Throughout this report you will gain information as to how temperature effects the amount of oxygen produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how

Auschwitz Concentration Camp Imagine that you were a 14 year old Jewish girl riding with your family and hundreds of other Jews and Gypsies packed into one tiny railroad car. You stop at an unfamiliar place were a man is screaming at you to get out. You have to watch your step getting out of the railcar because there are already dead people on the floor who passed on the trip here. Once you are out you are separated from your family‚ woman on one side men on the other. Kids are franticly

Enzyme Reaction Rates Under Different Conditions Introduction In this lab you will observe how the rate of a reaction is changed as certain factors are changed. You will observe how changing factors like temperature‚ pH‚ substrate concentration‚ and enzyme concentration changes the rate of an enzymatic reaction. In this experiment you will act as an enzyme by breaking toothpicks witch act as substrates. After observing the results of this experiment you will be able to determine what causes the

Enzyme assay lab report Health and safety: 4-nitrophenol is harmful. Introduction: Enzymes are quaternary structured proteins that are specific biological catalysts that speed up a reaction without being used up. They contain an active site that allows substrate to bind to a specific area on the enzyme which is of a complimentary shape of the substrate. There are two models of enzyme action‚ the Lock and Key model and the Induced Fit model. The Lock and Key model states that the enzyme has a specific

The great tragedy of what we know as World War two brought great danger to lots of people‚ but to not forget of what people themselves feared most‚ concentration camps. To be more specific in this case‚ the Auschwitz camps. In its time‚ it was the most effective camp of the Nazi regime. In this place‚ it consisted of three camps‚ each with their very own deadly purposes. The reasons this camp over all was the most effective was‚ history of its building‚ the day of a prisoner in the camps as well

Determination of the activation energy of an enzyme catalysed reaction Introduction In this practical the aim for this experiment was to find out the catalytic power of alkaline phosphate‚ as well as the rate of reaction and the activation energy of p-nitrophenol phosphate. Enzymes are biological molecules that catalyse a chemical reaction. ‘Enzymes work by lowering the activation energy of a chemical reaction making it easier to proceed’ [1]. This allows molecules to have more energy therefore

Principles of Biology Lab Exercise Enzymes: Catalysts of Life Instructor: Professor Alcendor By Shahid Rana Date: March 7th‚ 2013 Abstract: In this experiment we have demonstrated the function of enzymes. The whole experiment was devoted to understand how enzymes work as a catalysts and increase the chemical reaction without being used themselves. In general‚ enzymes are proteins that function as biological catalysts. These enzymes adhere to lower to amount of energy required for

temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate‚ protein‚ or fat‚ that the enzyme is designed

Hypothesis: If pH is increased or decreased past the enzyme’s optimum pH‚ the number of products produced by the enzyme will decrease because the enzyme will become denatured. Variables: The Independent variable is the pH of the environment. The uncertainty of pH is ± 1. pH is a unitless value. The Dependent variable is the number of products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant

experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs. Introduction: Enzymes are highly important because of the significant
