    substrate concentration‚ the enzyme is working at “maximum efficiency.” With a concentration at 40‚ it produced 2‚339 products. 2. The maximum velocity of a reaction is reached when the active sites are almost continuously filled. Increased substrate concentration after this point will not increase the rate. The reaction rate increases as substrate concentration is increased. It will soon level off though. 3. When the concentration is at low substrate‚ most of the enzyme molecules are not filled

    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

    of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme‚ the pH of the solution‚ the concentration of the enzyme‚ substrate and the product. Also‚ another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all‚ I have chosen to explain the effect of temperature and also the effect of inhibitors on enzyme activity

    to determine the optimum temperature range for the activity of the enzyme lactase. Extreme temperatures can have a detrimental effect on enzymes; very hot temperatures can cause the denaturation in the enzyme‚ which is the loss of protein structure. This causes a change in the shape of the enzyme leading to its inability to perform its function. As previously stated‚ the alternate hypothesis read: the optimal temperature range for lactase activity is between 23 to 25 ℃. The alternate hypothesis presented

    Research Question: How will an increase of FeSO4 concentration affect the activity of the enzyme catalase? Hypothesis: By increasing the concentration of FeSO4‚ there will be a decrease in the activity of the enzyme catalase because the Iron (ii) in the metallic ion will act as an inhibitor during the catalysis of the hydrogen peroxide into O2 and H2O. Introduction: We rely on oxygen to provide us with energy (ATP) and go through all the phases of aerobic respiration. However‚ oxygen can be

    reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second part of the prediction‚ that the rate will be lowest‚ the more acidic or alkaline the pH level is. For instance when the rate starts of

    Received July 18‚ 1997X A radiochemical enzyme assay for studying cyclooxygenase (COX)-catalyzed prostaglandin biosynthesis in vitro was optimized with respect to both COX-1 and COX-2 activity. The assay can be used to assess the relative selectivity of plant-derived inhibitors on COX-1 and COX-2. Assay conditions were optimized for both enzymes with respect to concentration of cofactors (l-epinephrine‚ reduced glutathione‚ and hematin)‚ activation time (enzyme and cofactors)‚ reaction time‚ and

    INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical
