Enzymes in the Digestive System Flashcards
What are the stages of carbohydrates breakdown
carbo (starch) > disacharides> monosach(simple sugars)
What are the stages of protein breakdown
protein > polypeptides > peptides > amino acids
What are the stages of lipid breakdown
lipid > fatty acid + glycerol
How many enzymes and where is starch broken down
3 types- in mouth and SI
Explain the breakdown of starch in mouth
Saliva amylase - (found in saliva made in salivary glands) breaks starch into disaccharides
Explain the breakdown of starch in SIntes
- pancreatic amylase (found in pancreatic juice made in pancreas) breaks starch into disaccharides
- intestinal amylase (found in intestinal juice, made in intestine) breaks disacharides into monosacharcides
How many enzymes and where is protein broken down
2 types- stomach and small intestine
Explain the breakdown of protein in stomach
pepsin (found in gastric juice and made in gastric glands) breaks protein into poly peptides
Explain the breakdown of protein in small intesine
- trypsin (found in pancreatic juice) breaks polypeptides into peptides
- peptidase (found in intestinal juice) breaks peptides into amino acids
How many enzymes and where is lipids broken down?
2 types, small intestine
Explain the breakdown of lipids in the small intestine
-pancreatic lipase (found in pancreatic juice) breaks lipids into fatty acids + glycerol
