    An enzyme is a tertiary globular protein. The function of an enzyme is to lower the activation energy of either the creation or breaking apart of a chemical bond. By lowering the activation energy of this process‚ the reaction of bonding‚ or in this case breaking apart‚ is sped up. An enzyme breaks apart the substrate in the active site of the enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case‚ the enzyme is catalase and the substrate is hydrogen

    demonstrates that the higher the concentration of enzyme used the greater the production of oxygen on the paper disc. The oxygen then produced on the disc gives it greater buoyancy allowing it to move past the markers faster. Aim To find the effect of the enzyme concentration on the reaction between Catalase and hydrogen peroxide. Introduction Enzymes are proteins that act as catalysts (a substance that increases or decreases the rate of a reaction) 2. Enzymes bind to a molecule called a substrate‚ converting

    The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

    RESEARCH Introduction There is approximately 75‚000 enzymes that exist in the human body. Enzymes are important for fast reactions that keep you alive‚ break down large molecules into smaller molecules and use small molecules to build large complex molecules like the enzymes that make DNA and enzymes also help cells to communicate with each other. I have decided to use not one but two enzymes to observe what happens to the different kind of enzymes when introduced to different PH (power of hydrogen)

    bleaches and cleansing wounds. In a cell its build up would be highly toxic. However‚ liver cells contain an enzyme‚ catalase‚ which immediately breaks down hydrogen peroxide. It is a peroxidase and breaks up the toxic hydrogen peroxide to water and oxygen which are both nontoxic. The reaction is exothermic‚ meaning that energy is released in the form of heat. It is the fastest known enzyme. Hydrogen peroxide  Water + Oxygen 2H2O2 2H2O O2 List of materials: Safety glasses Iron powder in a watch

    2BMT I. ABSTRACT pH greatly affects the activity of enzymes. There is a point or pH level where maximum activity of enzyme can be achieved‚ this is called optimum pH. Invertase was extracted from yeast and used as the detanured enzymes. Two sets of six test tubes were each added with different pH level of buffered solution: 1- 0.1‚ 2-0.3‚ 3-0.5‚ 4-1.7‚ 5-1.9‚ 6-1.11. On the first set‚ enzyme stock was added while on the second set denatured enzyme was added instead. Though this experiment was not

    metabolism to take place. The digestive system breaks down complicated food particles into molecules (Catabolism) like this: Fat breaks down into Fatty acids by using an enzyme called Lipase. Protein breaks down into Amino Acids by an enzyme called protease. Starch breaks down into sugars by using an enzyme called amylase. These enzymes are produced by hormones. The hormones are activated when you eat. Once we have broken these down‚ we can then build them back up again into a collection of molecules

    determine the effect of various factors on the rate of reaction between an enzyme andits substrate‚ and also to determine the optimal ranges under which the enzyme activity ismaximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme willincrease until it reaches optimum pH range (pH 7) because the enzyme is less denaturedwhen it reaches the preferred pH level‚ and after this
