  • Amylase's Enzyme Interaction

    1026 Words  | 5 Pages

    catalysts, which lowers the activation energy without being consumed in the reaction. Enzymes are organic catalysts and consists of two parts, an active site, and a substrate. The active site acts like a lock where the substrate binds to the site as a key which is then converted into a product. Despite that enzymes are catalysts, there are environmental factors that can affect the rate of reaction and how the enzyme functions (Patton). The purpose of the lab is to be able to find the molarity of an

  • The Enzyme Catalase Experiment

    1751 Words  | 8 Pages

    The Enzyme Catalase Experiment Aim A series of experiments involving the enzyme Catalase has been performed in order to determine some of the enzyme's properties. The enzyme had its reaction rate found in different conditions. Variation of enzyme concentration, variation of pH, variation of temperature, and the effect of different concentrations of inhibitors were all tested. Increasing the enzyme concentration increased the reaction rate. An optimum pH and temperature were found for

  • Investigating Enzyme Activity

    3981 Words  | 16 Pages

    Investigating Enzyme Activity Aim: To investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) Variables: These factors could effect the rate of reaction on an enzyme: · pH · Concentration · Temperature · Surface Area pH - Enzymes function at different pH values. In neutral conditions the amount of oxygen gas given of in an enzyme-catalysed reaction will increase. An enzyme is affected by how much acid or alkali is

  • Enzymes in Brewing Industry

    1894 Words  | 8 Pages

    Enzymes in Brewing Industry Bioengineering Research Paper Enzymes are catalysts or proteins that are produced by a living cell, but in process are independent of the cell itself. There are two types of enzymes i.e 1) Cell Independent enzymes 2) Non-enzymic enzymes Enzymes are long chains of amino acids held together by peptide bonds. They exist in all living cells, usually controlling the metabolic process whereby nutrients are converted into energy. Enzymes are also catalyst, this mean

  • Enzyme Lab Report

    2179 Words  | 9 Pages

    Section 1. Introduction “Enzymes are proteins that have catalytic functions” [1], “that speed up or slow down reactions”[2], “indispensable to maintenance and activity of life”[1]. They are each very specific, and will only work when a particular substrate fits in their active site. An active site is “a region on the surface of an enzyme where the substrate binds, and where the reaction occurs”[2]. “Lactase is an enzyme that breaks down lactose, the sugar in milk. It is produced by the cells lining

  • Immobilized Enzymes (Yeast)

    2880 Words  | 12 Pages

    Immobilized Enzymes (Yeast) Abstract Catalase is an enzyme found in living cells and is used to break down peroxides. Yeast cells, which contain catalase, are used to catalyse the decomposition of hydrogen peroxide solution into water and oxygen gas. The yeast cells were immobilized in sodium alginate beads in this experiment. Immobilized enzymes are widely used in biotechnology processes. They can be reused and is more stable at extremes of temperature and pH, thus improves the economy

  • Enzyme Activity in the Catalase

    1803 Words  | 8 Pages

    The purpose of this experiment was to see if there would be enzyme activity that is in catalase, which is found in potatoes. How my partner and me did the experiment was very simple, we put the filter paper filled with catalase concentration in to five sets of hydrogen peroxide. We found that the more concentration of hydrogen peroxide there was the faster it would take for the filter paper to reach the top, and the lower to no concentration level of hydrogen peroxide was the slower it would go to

  • Investigation on the Enzyme Trypsin

    2374 Words  | 10 Pages

    Investigation on the Enzyme Trypsin An Investigation determining a factor affecting the rate of digestion of gelatin by the protease trypsin. Introduction An enzyme is a biological catalyst, which speeds up reactions. An example of this in the human body is trypsin (a protease produced in the pancreas and used in the stomach), which catalyses the digestion of gelatine, a protein. For this investigation, a photographic film will be the source of the gelatine. I will be able to identify

  • The Application of Enzymes in Industry and Medicine

    832 Words  | 4 Pages

    The Application of Enzymes in Industry and Medicine Enzymes are proteins, made up of polypeptide chains of amino acids. They are biological catalysts to regulate the speed of many processes, and are used in industry and medicine, but in different ways. Enzymes are globular proteins, with their structure held together by hydrogen bonds and can therefore be denatured easily if these bonds are broken. This is because their structure is very important in the way they work. They have an active

  • The Effectivity Of The Alkaline Phosphatase Enzyme

    879 Words  | 4 Pages

    Enzyme activity can be effected by a series of factors such as pH, temperature, and concentration of enzyme (Campbell, 2014). The purpose of this experiment is to determine the specific effects due to the change in pH, temperature, and concentration on the enzyme activity of the Alkaline Phosphatase Enzyme. The results displayed the effects of the Alkaline Phosphatase Enzyme due to the shifts in environment. The temperature shift revealed the enzyme’s optimal temperature for it’s to function ideally
