Digestive System, NUTRIENT DIGESTIONS & ENZYMES - Coggle Diagram

- - - - responsible for carb digestion
  - - - activated by enteropeptidase -- produced by the duodenum
- - - - protects mucosa
    - - protects mucosa
    - - cleaves pepsinogen to pepsin; also denatures proteins and kill microbes
    - - cleaved to pepsin, in order to digest proteins
    - - dilutes and dissolves ingested materials
    - - for the digestion of vitamin b12
  - - - chief cells
        
        secretes pepsinogen
        
        pepsinogen is the zymogen of pepsin and is cleaved by HCl to become active
      - parietal cells
        
        secretes H ions as HCl
    - - G cells
        
        secretes gastrin
        
        induces parietal cells ot make more HCl
        
        also induces sotmach contractions
- - - - by decreasing HCl and increasing bicarbonate
    - - slows digestive tract motility to increase time for enzymes to digest food
  - - - trypsinogen -> trypsin
        
        Trypsin then activates other zymogens
- - - - hydrolyzes starch into smaller sugars
    - - catalyzes the hydrolysis of lipids
- - - - MOUTH
        
        HYDROLYZES STARCH
        
        INTO MALTOSE AND DEXTRINS
  - - - DUODENUM
        
        HYDROLYZES STARCH
        
        INTO MALTOSE AND DEXTRINS
  - - - DUODENUM
        
        HYDROLYZES MALTOSE
        
        INTO 2 GLUCOSE
  - - - DUODENUM
        
        HYDROLYZES MALTOSE
        
        INTO 2 GLUCOSE
  - - - DUODENUM
        
        HYDROLYZES LACTOSE
        
        INTO GLUCOSE AND GALACTOSE
  - - - DUODENUM
        
        HYDROLYZES SUCROSE
        
        INTO GLUCOSE AND FRUCTOSE
- - - - HYDROLYZES SPECIFIC PEPTIDE BONDS
      - ACTIVATED/HYDROLYZED BY HCL
    - - STOMACH
  - - - HYDROLYZES SPECIFIC PEPTIDE BONDS
      - ACTIVATED BY ENTEROPEPTIDASE
      - ACTIVATES CHYMOTRYPSINOGEN INTO CHYMOTRYPSIN
    - - DUODENUM
  - - - HYDROLYZES SPECIFIC PEPTIDE BONDS
      - ACTIVATED BY TRYPSIN
    - - DUODENUM
  - - - HYDROLYZES THE CARBOXY END OF AMINO ACIDS
      - ACTIVATED BY ENTEROPEPTIDASE
    - - DUODENUM
  - - - DUODENUM
  - - - DUODENUM
  - - - DUODENUM
- - - - EMULSIFIES FATS
        
        IN DUODENUM
  - - - HYDROLYZES LIPIDS
        
        INN DUODENUM
