Digestive system (what are enzymes (different types of digestive enzymes…

- - - - in this diagram many glucose molecules make a starch molecule which is a type of carbohydrate and when the enzymes (amylas) act on the starch molecules it makes a maltose molecule which is made up of 2 glucose molecules and when the enzymes act on it again it breaks down into glucose which is carbohydrates simpilest form
- - - - new substances are formed
      - enzymes are used
      - chemical reactions take place
      - Example
        
        protein ------> Amino acids
        
        Fats ----> fatty acids + glycerols
        
        CHO ------> glucose
    - - breaks large food into smaller food
      - no new substances are formed
      - happens in the mouth, oesophagus and small intestine
- - - - TYPE OF MOLECULE DIGESTED
        
        CHO e.g starch --> maltose
      - OTHER FUNCTIONS
        
        Teeth break the food into smaller pieces. tounge rolls the partly digested food into oesopahgus
      - TYPE OF SECREATION
        
        saliva ---> salivary amylase
      - TYPE OF DIGESTION
        
        physical digestion
        
        teeth is used to break down the large peices of food into small pieces of food and the tounge rolls the partly digested food into the oesophagus
        
        chemical digestion
        
        salivary amylase is used to break down the starch into maltose in the mouth
    - - TYPE OF DIGESTION
        
        PH.D
      - OTHER FUNCTIONS
        
        pushes the food into the stomach (peristalsis)
    - - TYPE OF MOLECULES DIGESTED
        
        long protein chains ----> smaller protein chains
      - TYPE OF SECREATION
        
        gastric juice
        
        hydrochloric acid
        
        water
        
        enzymes (proteas)
      - TYPE OF DIGESTION
        
        Both are taking place
      - OTHER FUNCTIONS
        
        muscular bag
    - - TYPE OF DIGESTION
        
        chemical digestion
        
        physical digestion
        
        when bile juice breaks down large fat droplets into small fat droplets
      - TYPE OF MOLECULE DIGESTED
        
        remaining CHO, maltose -----> glucose
        
        fats -----> fatty acids + glycerols
        
        small protein chains ---> Amino Acid
      - TYPE OF SECREATION
        
        pancreatic juices, intestinal juices
        
        carbohydrase
        
        lipase
        
        Amylase
        
        protease
      - OTHER FUNCTION
        
        glucose, Amino asids, fatty acid + glycerols -------> absorbed into the walls of the small intestine
      - classifed
        
        duodenum
        
        ileum
    - - TYPE OF DIGESTION
        
        None
      - OTHER FUNCTION
        
        water + minerals -------> absorbed into the bloodstream
        
        undigested food + excess mineral and water = faeces -------> stored in the rectum and released through the anus
      - classified
        
        rectum
        
        colon
  - - - pancreas
        
        creates pancreatic juice
        
        contains enzymes which are amylase, carbohydrase, lipase and protease
      - liver
        
        creates bile juice
        
        blie juice is a juice which breaks down large fats droplets into small fats droplets in the small intestine
      - gall bladder
        
        stores bile juice
    - - hepatic duct transport bile juice from the liver to the gall bladder
      - bile duct transport the pancreatic and bile juice to the small intetine
      - pancreatic duct transport the pancreatic juice to the bile duct
