    energy required. An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Enzymes carry out the thousands of chemical reactions that occur on cells, or the basic units of structure and function of an organism. Usually, they are polymers of thousands of amino acids. Enzymes are not used up as it carries out the reaction but are recycled over and over. In this experiment, peroxidase from horseradish was the enzyme used to test…

    at which enzyme activity is most effective is approximately at 40℃. This result was expected as this trial temperature was closest to internal body temperature, 38℃, and as catalase is present in all body organs (T. Fouad, Antioxidants). Temperature affects chemical reactions by increasing the kinetic motion of molecules and changing the rate of collisions between them. In lower temperatures, kinetic motion is decreased and there are not enough collisions between the molecules for enzyme…

    The lab that is being preformed is about digestive enzymes. Enzymes are protein molecules produced by living organisms that speed up a specific chemical reaction in the body. There are also digestive enzymes which digest our food. Our bodies make digestive enzymes in the pancreas, stomach, small intestine, and mouth. Digestive enzymes break down the food we eat into nutrients so that our bodies can absorb them. There are different digestive enzymes that digest certain macromolecules such as…

    1. Where do restriction enzymes come from and what is their original purpose? Restriction enzymes come from bacteria. Bacteria used restriction enzymes to cut up DNA into fragments to fight off viruses. 2. a. Why do you get different fragment sizes if you cut the DNA from two different species with the same restriction enzyme? Each species has a different arrangement of bases, and the restriction enzyme only cuts after a specific order of bases. Due to that being the case, the specific…

    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…

    INTRODUCTION: The objective of this lab is to measure the activity of an enzyme and the effects of environment conditions on enzyme activity. Enzymes are catalysts; agents that speed up chemical reactions by lowering the activation energy required. This means that a catalyst helps reactions occur at a greater speed and lower temperature. For this lab report we focused on the enzyme Tyrosinase, Tyrosinase is an enzyme that produces melanin from the amino acid tyrosine. Three different reactions…

    An enzyme is a protein catalyst, whose basic function is to increase the rate of the reaction, meaning lowering the activation energy. Because the body creates enzymes to be as specific as possible, in order to prevent inefficiency and careless mistakes, most enzymes come in direct contact with only one substrate to produce products. Enzymes will work on creating substances until the reaction is complete or the particular enzyme is inactivated, which either means being destroyed & recycled or…

    Enzymes are a biological catalyst. When a chemical reaction is taking place the enzyme works to lower the activation energy of a reaction. The activation energy is, the amount of energy that is required in order for a reaction to take place. Enzymes bind to reactant molecules. The enzymes hold these molecules in a way that makes the processes of the chemical bond-breaking and bond-forming take place more readily. A reaction can be either energy-releasing or energy-absorbing. Enzymes have no…

    The catalytic effect and specificity of enzymes 1.Introductions to enzymes Enzymes are proteins that can react with their specific substrates to achieve an highly effective catalyst reaction. .Almost all cellular activities of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts,enzymes provides another reaction route requires lower activation energy (Ea) to increase the number of particles that have a kinetic energy of not less than…

    introduce the basics of enzymes. The topic is important because they are in every living cell and because of enzymes chemistry is allowed in the cell. They do this by providing the energy needed for chemical bonds to break down and lets molecules interact with each other. For part 1 of the lab my hypothesis was if you increase the concentration, then the absorbance will also increase. For part 2 section A my hypothesis was if you increase the temperature, then the enzyme reaction time will also…
