The Influence Of Enzymes

Improved Essays
Enzymes are substances produced by living organisms that act as catalysts to reduce the activation energy required for a chemical reaction. By lowering the activation energy, enzymes speed up the chemical reaction by providing an alternative action pathway (“Enzymes”). Enzymes are required in minute amounts because they remain unchanged after a reaction has occurred, so the same enzyme molecules can be reused over and over again.
Since enzymes are proteins, they have active sites that speed up the reaction and are therefore highly specific in their action. Enzymes must also be kept in very particular conditions as they can be affected by temperature and pH. Up to a certain point, the rate of an enzymatic reaction will proportionally increase with increasing temperature (Campbell, et al. 2010). If the temperature were to increase too high, the hydrogen bonds holding the protein in it’s structure would break and the enzyme would begin to denature, causing the active site to change shape (Adam-Day 2015). Enzymes are important because the control the speed of reactions in your body, and without them, the reactions would occur too slowly to keep us alive.

For example, when we were working with the reaction chamber, we could see gas leaving the chamber from a small hole at the base of the ‘straw’ that lead into the chamber. If that gas had been collected, we would have had more accurate data. This could be resolved by testing the chamber before hand to be certain that there are no gaps in the stopper and the chamber before the experiment is performed. We also struggled with using the graduated cylinder as a measuring apparatus so some oxygen produced may have escaped into the environment instead of into the cylinder. This could be resolved by being prepared for the flip of the chamber and having the cylinder prepped before the flip has even

    By adding more temperatures, the results become more precise as to what temperature amylase denatures at, and what temperature is the most efficient for amylase. Variations that differ from the variables in this experiment could be the effect of pH levels on enzyme activity, which would show the best pH levels for amylase to be most efficient and whether it works best at low, medium or high pH levels. The concentration of amylase would also be a variation that would show whether amylase works faster if there is more of it or not. If all of these variations were done, it would show in what conditions amylase works best at, and if the human body fits those conditions or…

    Enzymes are protein molecules that significantly speed up the rate of virtually all of the chemical reactions that take place within the cell. In the following lab was to examine an enzyme that is found in pineapples. That enzyme is bromelain its breaks down protein into their protein into their amino acid by a process of hydrolysis. They are found in tropical areas like Hawaii, Thailand, and Brazil. For the first experiment the hypothesis was that the when gelatin was added to the water, fresh pineapple juice, and canned pineapple juice and submerged into the ice chest the solutions would turn into Jell-O.…

    A chemical reaction’s rate is described by the amount of product formed. Substances that increase that rate are called catalysts. Catalysts are often proteins called enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points.…

    The effect of altering temperature on the rate of liver enzyme activity is measured in this experiment to be able to visualize how temperature in the environment and in the body can manipulate the rate of enzyme activity. Enzymes are protein catalysts that lower the amount of activation energy required to start a biochemical reaction. According to Dr. Meyertholen (2015), enzymes are structured to work with certain substrates, meaning that the structure determines the function of the enzyme. If the enzymes shape is altered, they become denatured. Denaturation of an enzyme can occur with changes in factors such as temperature, pH, or salinity.…

    Introduction: Enzymes are biological molecules that act as a catalyst to significantly speed up the rate of the chemical reactions that take place within cells without being used up in the process. According to the website, www.ducksters.com, “enzymes are special types of proteins. Like all proteins, enzymes are made from strings of amino acids. The function of the enzyme is determined by the sequence of amino acids, types of amino acids, and the shape of the string.” Along with this we need to know about a peroxidase; “A peroxidase is one of a number of enzymes that act as catalysts to allow a variety of biological processes to take place.…

    The prediction for enzyme activity was that enzyme activity would begin fast and then gradually decrease. This was tested with catechol oxidase and catechol and resulted in a trend that increased then slowed down over the course of ten minutes. The other experiment was to test the rate of enzyme activity with different substrate levels over the course of five minutes. The prediction stated that the initial reaction rate will increase with substrate concentration. The results supported the hypothesis by presenting an increase in mole product over time as substrate levels…

    In most cases, a chemical reaction is able to occur in more than one way; enzyme kinetics studies the effect of how biological catalysts can influence biochemical reactions. Enzymes play an important role in regulating metabolic pathways in the human body and without enzymes they will not function efficiently. The rate of a reaction is enhanced by enzyme activity which provides alternate pathways for the reaction to proceed by.…

    The temperature is too low inside many living things, which makes it hard for biochemical reactions to happen at a faster rate. Enzymes help biochemical reactions speed up. An enzyme works by lowering the amount of activation energy needed to start a chemical reaction. Activation energy is the minimum amount of energy needed for the reactants to begin a chemical reaction. Normally, biochemical reactions would take many days, but with enzymes doing their job correctly, the same reaction is able to happen in seconds.…

    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.…

    For pH, it was hypothesized that the optimal pH would be 7. As temperature was increased, the enzyme activity also increased. Because temperature is the measure of kinetic energy, an increase in temperature would cause an increase in kinetic energy. This means that particles are moving quickly with high entropy, which causes more collisions to happen. Due to this, there is a higher probability of substrates colliding with enzymes, thus making the reaction occur.…
