    Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

    Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

    correlation between catalase concentration and the rate of reaction. This occurs because as the enzyme concentration increases‚ there are more enzymes available to catalyze substrates. More enzymes means more reactions can take place at a time‚ thus a faster rate of reaction. Overall‚ based on the results of table 2.0 and graph 2.0‚ it is prevalent that there is a positive correlation between the concentration of enzymes and the rate of

    for the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity

    Factors Affecting Enzyme Activity Abstract: In the following lab factors affecting enzyme activity‚ temperature‚ pH‚ enzyme concentration‚ substrate concentration and surface area will be tested on a beef liver enzyme to see if there will be any effect of performance. By doing 2 or more trials the results will show whether there is an effect to the enzyme from the following factors or not. Some of the factors may denature the enzyme and some will do nothing. Using a table qualitative and the

    Enzymes are organic catalysts; where a substance speeds up the rate of chemical reactions without changing being changed by the reactions. In lab they tested this by seeing how H2O2 and the catalysts from the banana and liver react to make H2O+O2. Depending on different conditions; like decomposition of H2O2 (surface area)‚ temperature on function‚ reusing the catalase‚ reaction rate of iced liver returned to room temperature‚ and effects of pH on enzyme activity‚ to see how much O2 was released

    Introduction Enzymes are key players in metabolism. A metabolism is the organic processes in a cell or an organism that are necessary for life. An enzyme affects the rate at which a reaction occurs when the activation energy is lowered. In this reaction the reactant is called the substrate which is that combine with enzymes molecules to form a temporary enzyme substrate complex. During this products are formed and the enzyme molecules released is unchanged. For the substrate complex to form the

    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
