Enzymes and digestion

    Cards (24)

    • What are the substances produced in digestion that mix with food?
      Digestive enzymes
    • What is the primary function of digestive enzymes?
      To break down big molecules
    • What do carbohydrases convert carbohydrates into?
      Simple sugars
    • What is an example of a carbohydrate that is broken down by amylase?

      Starch
    • Where is amylase produced?
      In the salivary glands, pancreas, and small intestine
    • What do proteases convert proteins into?
      Amino acids
    • Where are proteases produced?
      In the stomach, pancreas, and small intestine
    • What do lipases convert lipids into?
      Glycerol and fatty acids
    • Where are lipases produced?
      In the pancreas and small intestine
    • How does the body utilize the products of digestion?
      To make new carbohydrates, proteins, and lipids
    • What is the role of glucose in the body after digestion?

      It is used in respiration
    • What is the function of bile in digestion?
      To neutralize stomach acid and emulsify fats
    • Where is bile produced and stored?
      Produced in the liver and stored in the gall bladder
    • Why is bile alkaline?
      To neutralize the acidic pH from the stomach
    • How does bile aid in the digestion of fats?
      By emulsifying fats into smaller droplets
    • What are the main digestive enzymes and their functions?
      • Amylase: Breaks down starch into simple sugars
      • Protease: Breaks down proteins into amino acids
      • Lipase: Breaks down lipids into glycerol and fatty acids
    • Describe the process of digestion in the human body.
      1. Food enters the digestive system.
      2. Enzymes break down food molecules.
      3. Nutrients are absorbed into the bloodstream.
      4. Waste is stored for removal.
    • What is the pH level of the stomach acid?
      Approximately pH 2
    • What is the role of the stomach in digestion?
      It pummels food and produces protease enzyme
    • What is the function of the gall bladder?
      To store bile before it's released into the small intestine
    • What is the role of the large intestine in digestion?

      To absorb water from the food
    • What is stored in the rectum before excretion?
      Faces made up mainly of indigestible food
    • What is the significance of the digestive system being a continuous tube?

      It allows for the efficient processing of food and absorption of nutrients
    • What are the three parts of the digestive system that produce proteases?
      The stomach, pancreas, and small intestine
