Digestive System Flashcards
Pancreas
Bicarbonate - neutralizes HCl
Trypsin - converts big proteins into smaller proteins
Pancreatic amylase - Continues breakdown of amylose into maltose
Lipase -breakdown fat into fatty acids and glycerol
Liver
Bile - emulsifies fat (physical break fat into smaller pieces)
Small intestine
Peptidases - converts small proteins into amino acids
Maltase - breakdown of maltose into glucose
Large intestine
Absorbs water, minerals and some vitamins
Stomach
Churning in stomach physical
Pepsin - begins digesting proteins
HCl - Lower pH of stomach so pepsin can work, helps breakdown proteins
Mucus - protects stomach from hydrochloric acid
Mouth
Physically - breaks down food using teeth
Chemically - saliva glands secrete saliva which contains
- water
-mucus
-amylase - breaks down amylose into maltose
Carbohydrates :
Main source of fuel your body uses for energy
(Energy source and structural support.)
Disaccharides
Sucrose
Lactose
(Maybe Maltose)
Polysaccharides
Starch - Energy storage
Cellulose - structural support in plant cells
Glycogen - energy storage
Lipids/Fats
Long term energy absorbs fat soluble vitamins
(Long-term energy storage, insulation, and cell membranes.)
Fats, Oils, Waxes
Triglycerides
= glycerol and 3 fatty acid chains
Saturated - straight chain
Unsaturated - bent chain
Proteins
Enzymes, structural support, transport, defense, hormones.
Insulin, hemoglobin, collagen, antibodies, enzymes
Made of Amino acids - 20 different amino acids 8 are essential ( cannot be made by body).
