    Importance of Enzymes

    • 605 Words
    • 3 Pages

    Enzymes and Their Importance in Plants and Animals Enzymes are large proteins that are responsible for catalysing thousands of metabolic processes that sustain life. Enzymes work similarly to those catalysts used in industry by lowering activation energy and therefore dramatically speeding up the rate of a reaction‚ however‚ these biological catalysts are highly selective to their substrate. Almost every chemical reaction that occurs in a cell requires enzymes in order to occur at rates required

    Enzymes control the rate of metabolic reactions‚ they act as biological catalysts‚ which means they are used but not used up and they also control the speed of the reaction. Enzymes are proteins which means that anything that disrupts this structure such as high temperature or change in pH will affect the enzyme activity. There are many factors affecting enzyme action for example temperature effects them‚ if the Increasing the heat gives molecules more kinetic energy so they vibrate this can then

    Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

    What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However‚ different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body‚ there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it

    it’s lowest to do so. However‚ in cold solutions the starch will take longer as it will in temperatures beyond 40 degrees. Once it reaches this point‚ the break down will either take a very long period of time or have no reaction at all as enzymes are denatured at a certain point.

    amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal pH. The pH affects the charge of the amino acid at the active site. PH changes affect the structure of an enzyme molecule and therefore affect its ability

    Enzymes (pron.: /ˈɛnzaɪmz/) are large biological molecules responsible for the thousands of chemical interconversions that sustain life.[1][2] They are highly selective catalysts‚ greatly accelerating both the rate and specificity of metabolic reactions‚ from the digestion of food to the synthesis of DNA. Most enzymes are proteins‚ although some catalytic RNA molecules have been identified. Enzymes adopt a specific three-dimensional structure‚ and may employ organic (e.g. biotin) and inorganic (e
