    Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

    effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water. We measured

    BIO 5 Lab Report: Lactase Enzymes Enzymes are biological catalysts or assistants. Enzymes consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. Enzymes can either launch a reaction or speed it up. The chemicals that are transformed with the help of enzymes are called substrates. In the absence of enzymes‚ these chemicals are called reactants. Enzymes are thought to have an area with a very particular shape. When a molecule of

    The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

    Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pHenzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where

By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase too‚ indicating a faster rate of reaction. Experiment 2 (Effect of pH): Enzymes are affected
