Enzymes are true catylst that exist in the living matters, helping to speed up the reactions and to keep up the metabolisms within the cell. Enzymes will work properly when working in favorable condition and with substrates that will bind easliy to form products. Enzymes bind to specific sustrates for form specific product(s) in different parts of the cell. These happens in the active site where chemical reaction begain as substrates are binded to the enzymes. Enzymes have different shapes, bond attractions or size that will fit to particular substrates and may also cause configuration changes within the enzymes that produce products. Different enzymes have different properties where the reactions may be vigrous or happens in stable manner in certain time period. …show more content…
There are two type of inhibitor one is competetive inhibitors that compete with substrates to bind with the enzymes, this can result in low velocity of enzyme and the product formation. While non-competetive can bind to another active site of the enzyme incrasing the velocity and substrate concentrations.
These are measured by using Michaelis-Menten Kinetics formula, the equation measures the substrate concentration verses the velocity of an enzyme to show the relation between velocity and substrate concentration. However when enzyme reaches it maximum capacity it remains constant and this known as Vmax. Vmax and Km are correlated to each other because Km is half of the Vmax and amount of substrate concentration of reaction. The Michaelis-Mention equations will show curve on the graph and also determine the physical condition and the flow of the concentration of the enzymes and their

    What is the ideal pH for its functionality? Is the activity of the enzyme affected by the temperature? Is tyrosinase identify by using electrophoresis? Hypothesis for the experiments are as follow: if tyrosinase is place in a pH of 6 will it continue to function normally and will light be absorbed at 475nm. If tyrosinase is put in a pH of 4 or 8 can the function be hindered if it’s not arrested completely?…

    Catalase Enzyme Lab Write-Up Our goal with this lab is to discover how enzymes affect the production and destruction of harmful chemicals our body makes into harmless chemicals. Our body contains hundreds of enzymes in our cells and this lab will show us how they interact with parts and materials of our bodies. The enzyme we will be focusing on is called catalase. It’s job for the body is to break down hydrogen peroxide a harmful substance into two harmless substances oxygen and water.…

    The different jobs that Enzymes do rely on the temperature, ionic conditions, and PH level of the environment. Enzymes work in different environments. For instance, some enzymes function better with acidic PHs while others are better in less acidic, or neutral surroundings. In many organisms, enzymes are extremely important because the various biochemical reactions occurring in the organisms need enzymes to speed up the chemical…

    Enzymes are proteins that act as catalysts and help chemical reactions occur everywhere in life and throughout body. A catalyst is a specific type of protein that increases the rate of a chemical reaction. In an enzyme reaction, the substance that the enzyme acts upon is called the substrate. The enzyme has a special area called the active site, which is a particular point in the substrate at which a reaction occurs. The active site has specific shapes that match up with the enzymes to cause the reactions.…

    Enzymes Two major factors influence how effective an enzyme is by promoting the rate of reaction. Each enzyme has a specific temperature that allows it to perform the most work. If an enzyme is placed in an environment under its optimal functioning temperature, the speed of the reaction will slow. Reason being, the molecules of the reactants reduce in energy from the low temperature, less movement means less reactions with the enzymes. At higher temperatures, molecules within an enzyme increase in rate.…

    Each enzyme is formed of polypeptide chains that wind and bend to form complex grooves and valleys. These grooves are the active sites. The active site is where the substrate will fit perfectly. Certain things can change or denature, or breakdown, an enzyme. Some of these factors include variations of pH levels, temperature, and the presence of inhibitors.…

    Enzymes are catalysts that contain proteins. Catalysts are the part of the product that speeds up a reaction. Only reactions can occur when the right enzyme ends up finds the right material to produce a process. A low pH is a good environment for an enzyme as well as a low temperature. After the reaction, no enzymes are used up.…

    Discussion: The specific purpose for this study was to see how enzyme activity would change as there was a change in temperature and pH. Both temperature and pH were hypothesized to have an affect on enzyme activity. Each had an optimal temperature. At this point, the rate of enzyme activity would stop increasing and begin to decrease. For temperature, it was hypothesized that the optimal temperature would be 48°C.…

    The purpose of conducting this experiment was to explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it took for the reaction to occur. To investigate the effect of the concentration of the substrate on the reaction time, four test tubes were used.…

    Discussion In this study, the Catechol enzyme was studied under the conditions of varying pH, temperature, substrate concentration, and enzyme concentration. In Figure 1, the data suggested that the trend was neither directly nor inversely proportional, but the highest activity rate was at 24°C. Most enzymes denatured at higher temperatures of approximately 40°C, which led to the inability to see any color change (Helms et al., 1998). At lower temperatures, the enzyme was somewhat efficient because molecules move slower at lower temperatures, so enzymes lost productivity.…

    By calculating the rate of reaction and studying the effects of varied conditions on the reaction, a great deal can be learnt about the enzyme, including how the enzyme could be inhibited, the catalytic mechanism of the enzyme etc. One of the most well-known ways to look at enzyme kinetics is the Michaelis-Menton equation, which relates reaction rate (V) to concentration of substrate ([S]). Its equation can be used to work out the maximum rate of reaction of the system (Vmax) and the substrate concentration at which the reaction rate is half of Vmax (Km, also known as the Michaelis constant). Michaelis-Menton shows that the rate of reaction is dependent of the rate of formation of the enzyme-substrate complex and rate of formation of the product. This means that in the enzyme assay, the rate of reaction is dependent on the formation of NAD+ from NADH (Scopes, R.,…
