digestive enzymes Flashcards
- digestive system (18 cards)
define an enzyme?
a protein that acts as a biological catalyst
what are the two models we use to understand enzymes?
lock and key model and
induced fit model- both models show how the substarte binds with the active it and the enzyme
what part of the cell synthesises enzymes?
ribosones
what type of digestion are enzymes involved in?
chemical digestion
where can we find these digestive enzymes?
mouth- amylase
stomach- protease/ hydrochloric acid and small intestine
what is protease?
enzyme that catalyses the digestion of proteins
what can amylase digest
starch into simple glucose
where is amylse produced?
salivary glands, pancreas and small intestine
what is protease catalyst?
the digestion of proteins into amino acids
where is protease produced?
stomach- pepsin
pancreas
small intestine
lipases enzymes?
digesion of lipids (fats) to fatty acids and glycerol
what is the role of digestive systems?
to digest large insoluble molecules into small soluble molecules that can be then absorbed into the bloodstream

- stomach
- small intestine
- pancrease
what organs does protease work tho?
- stomach and small intestine
what organs produce lipase?
- pancreas
