enzymes

    Cards (19)

    • what are enzymes?
      • enzyme increase the reaction of speed
      • they are often called biological catalysts
    • what is the active site?
      for the reaction to speed,the subtrate only bends to specific enzymes
    • what are factors that affect the rate of enzymes?
      • pH-have an optimum of pH,if the pH changes away from the optimum pH,then the enzyme decrease,if the pH is to high or low the enzyme will denature
      • temperature-enzymes have a optimum temperature,if it past the temperature the active site will change the shape and the enzyme will denature
    • what are enzymes in digestion?
      • are produced by specialised cells
      • they are situated in the glands and the lining of the gut
      • they are then secreted out of the body cells and into the cavity of the digestive system
    • how do the enzymes breakdown large food molecules?
      • the digestive enzymes catalyse a large amount of food into smaller molecules of food
      • then they are absorbed into the bloodstream
      • digested molecules can be used to construct new carbohydrates,proteins and lipind in the body
    • what are the 3 main enzymes in the body?
      • amylase
      • protease
      • lipase
    • what is amylase?
      amylase is a type of carbohydrase that breaks down starch
    • where is the amylase site?
      • the small intenstine
      • the mouth
    • where is amylase producted in?
      • small intenstine
      • pancreas
      • salivary glands
    • what is the amylase purpose?
      when amylase breaks down the starch,maltose and other sugars are produced
    • what are protease?
      • protease are digestive enzymes that breaks down proteins into amino acids
    • what are protease purpose?
      protease breaks down into amino acids
    • where are amino acids produce in?
      • small intenstine
      • stomach
      • pancreas
    • what are action site of protease?
      • small intenstine
      • stomach
    • what are lipase?
      is a type of enzymes that breaks down lipids into glycerol and fatty acids
    • where are lipase production?
      • small intenstine
      • pancreas
    • what is bile?
      bile is an alkaline substance produced in the liver and stored in the gallbladder
    • why are bile important?
      • enzymes in the small intentistine operates the best in alkaline condition
      • stop enzymes to denature by neutralising the stomach acid
    • what is emulsification?
      • bile breaks up fats into tiny droplets
      • the tiny droplets have a high surface area
      • this increase the rate of lipase
