    Enzymes are biological highly selective catalyst, greatly accelerating both the rate and specificity of metabolic chemical reactions, from the digestion of food to the synthesis of DNA. Enzymes catalyze chemical reactions involving the substrate. Substrate is a molecule that attach to the active site of the enzyme protein which an enzyme acts. Active site is a small port in an enzyme that helps enzyme to bind with substrates and undergo a chemical reaction. During this binding of substrates with…

    Introduction Enzymes are specialized proteins present in all living organisms, whether animals, plants or microorganisms (Reece et al., 2012) .In addition, life would cease to exist without these vital organic molecules, as they are needed for metabolic processes, and other reactions and processes in the body (Reece et al., 2012). Sometimes some RNA molecules can act as enzymes (Reece et al., 2012). Enzymes as well as their substrates work best at optimal levels, and are affected by temperature…

    Lactose is a sugar found in milk and milk products. Lactase Is an enzyme found in the small intestine that breaks down lactose into simple sugars such as glucose. The substrate has to fight to bind with the enzyme lactase. The inhibitor tries to attach to the lactase and slow down the chemical reaction while the substrate does the opposite. The substrate increases the rate of the chemical reaction, this chemical reaction breaks down the lactose into sugars. This chemical reaction is imperative…

    The first enzyme to be inactivated by ultrasonic waves was pepsin about 60 years ago and the mechanism of inactivation was cavitations (Geckeler, 2009). Heat was the common method used in inactivation of enzymes, however, was observed to lower the quality of the preserved food as well as destroying food nutrients. Ultrasound is being tested as an alternative in enzymatic inactivation (Geckeler, 2009). Since 60 years ago ultrasound has been observed to be an efficient method in enzyme…

    The role of enzymes play a large role in the survival of organisms through catalysis of reactions that keep them alive and functioning. The purpose of this experiment was to measure reaction activity over time and how substrate concentration affects their activity level. A supernatant was made through the dilution of blended potato extract. Then the supernatant was mixed with catechol and the reaction rate was measured in units of absorbance through a spectrophotometer every 30 seconds for ten…

    Enzymes are important substances made by the cells of plants and animals. There are called catalysts, which are substances that control how quickly chemical reactions occur without interfering at the reaction products (Daja and Treska 2015). Structure of both the enzyme and substrate, the substance on which an enzyme acts; provides clues as to how an anticipated reaction can be favored by the alignment of catalytic residues (Johnson 2008). The reaction of an enzyme is represented as: In…

    Introduction: The primary purpose of this experiment was to find how enzymes affect the reaction rate. During the experiment, factors such as: amount of enzyme, substrate concentration, and pH were tested to find a correlation with enzyme activity. Enzymes, which in the experiment was peroxidase extracted from turnip, are protein catalysts that break up the substrate, which in this experiment was hydrogen peroxide. If there is a correlation between the environmental factors, there should be an…

    In general, enzyme thermostability is an intrinsic property, determined by the primary structure of the protein. However, external environmental factors including cations, substrates, co-enzymes, modulators, polyols and proteins often increase enzyme thermostability. With some exceptions, enzymes present in thermophiles are more stable than their mesophilic counterparts. Some organisms produce enzymes with different thermal stability properties when grown at lower and higher temperatures. There…

    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,…

    definition an enzyme are biological catalyst that facilitates specific chemical reactions. What this means is that an enzyme is a protein its function is to function as catalyst which lowers the activation energy for the reaction to occur quicker. Enzymes have different ways that it reacts with substrates. One way is that an enzyme reacts with a substrate is by bringing two substrates together correctly or by stressing particular bonds of substrates. By doing on or the other an enzyme can lower…
