  • Effect Of Enzyme Concentration On Enzyme Activity

    Catalysts speed up the rate of a reaction without being consumed in the process4. Enzymes are proteins that act as catalysts to a given biochemical reaction4. Enzymes manage to expedite metabolic reactions by lowering the activation energy required for the reaction to proceed4. In ideal conditions, the reactant macromolecule binds and acts on what is referred to as a substrate. However, enzymes require specific conditions specific conditions to perform most effectively4. Enzymes are susceptible to altering their optimal form and structure in unfavorable conditions so they are incapable of binding with the substrate4. Conditions like temperature and pH most prominently affect an enzyme’s functionality. Generally, at a temperature…

  • Enzyme Activity

    nature of digestive enzymes. Enzymes are proteins that act to catalyse reactions in order to bring about a specific change or effect. Enzymes are specific which means each enzyme has a particular purpose and reaction to catalyse (BBC, 2014). This is due to the substrate that the enzyme acts with that has a particular shape to connect with the enzymes active site. The way enzymes work and fit together can be demonstrated through a lock and key model (refer to figure 1). In this analogy the lock…

  • The Importance Of Enzyme

    II. Introduction An enzyme is a specific type of macromolecule known as a catalyst, that accelerates the rate of chemical reactions by taking part in the reaction without being consumed (Wilson, et al 2015). Enzymes participate in these reactions inside the cell and decrease the activation energy required to begin the reaction. These catalytic agents bind to substrates that are changed into products. A component of the enzyme that is responsible for binding to substrate or the reactant is…

  • The Importance Of Enzymes

    Enzymes are found in all living organisms. They are present to speed up or accelerate a chemical reaction; referred to as a catalyst in a chemical reaction. They are essential to obtain rates to sustain life as without enzymes rates would be too slow to provide for life. Molecules at the start of the process are called substrates, the enzyme will then convert these into changed molecules which are called products, after this process the enzymes maintains the same shape. (Berg et al. 2002).…

  • Enzyme Experiment

    In this lab we learned the basics of enzymes and how they work. We were able to perform a quantitative assay of the activity of an enzyme in a tissue extract using a spectrophotometer. Also, we had to organize the data that was provided into tables and graphs so we could have the ability to test a few hypotheses. For example, we tested the whether the rate of the reaction was influenced by enzyme concentration, whether the activity of the enzyme was influenced by temperature and also too see if…

  • How Does Enzyme Affect Enzyme Activity

    i. Enzymes are macromolecules that increase chemical reactions without being consumed in the reaction. They do this by lowering the activation energy (the amount of energy that reactants need to absorb in order for a chemical reaction to take place). Every enzyme has a substrate with a unique shape and structure for it to bind to. Denaturation of proteins (when a protein unravels and becomes inactive), and change in the shape of the enzyme or substrate all influence the activity and…

  • Potato Enzyme Experiment

    discover their effect on the enzyme catalase, taken from a cut and blended potato. The blended potato mixture was strained and put into a centrifuge, the liquid that was in the centrifuge contained the enzyme and remained on ice. The enzyme was placed in test tubes that had varying levels of pH buffers, substrate concentrations and temperatures; the pH, substrate concentration and temperature were the three variables. The data showed that each variable contained an optimum level at which the…

  • Enzyme Lab Report

    The objective of this lab was to see how enzymes were used, use the scientific method, and how enzymes are affected by temperature. Introduction Proteins which constitute enzymes in their final form are macromolecules that make up large amounts of living organism which are called polymers which are made up of many different monomers. An enzyme is a biological catalyst that increases the rate of a reaction by lowering activation energy. Activation energy that the enzyme uses id an energy barrier…

  • The Importance Of Enzyme Kinetics

    Enzymes are known as catalysts that cause reactions to occur more rapidly by lowering the reaction’s activation energy. A reaction’s activation energy is known as the minimum amount of energy required to get a chemical reaction started1. In order for cells to efficiently manage thousands of different chemical reactions, they make use of biological catalysts. Without these catalysts, biological reactions would not be able to proceed at a proper rate necessary to maintain life. Most, but not all,…

  • Cofactor And Enzyme Reaction

    Introduction What are enzymes and how do they affect reactions? Enzymes force reactions, in cells, to maintain a speed necessary for life. Enzymes can also be considered catalysts because they require the reactions to arise faster without themselves changing. For this experiment, the substrate in the enzymatic reaction was sucrase, and it will be causing sucrose to change resulting in the following equation: Sucrose → Glucose + Fructose Where the arrow is in the equation indicates the enzyme,…
