Enzymes and Digestion Flashcards
what do digestive enzymes do
break big molecules into small soluble molecules, that can be easily absorbed into the bloodstream
what is an example of carbohydrases
amylase
what does amylase break down
starch
what is starch converted into
maltose
which 3 places is amylase made in
salivary glands, pancreas, small intestine
what is an example of proteases
protease
what does protease break down
proteins
what is protein converted into
amino acids
which 3 places is protease made in
stomach, pancreas, small intestine
what is an example of lipases
lipase
what does lipase break down
lipids
what is lipids converted into
glycerol and fatty acids
which 2 places is lipase made in
pancreas, small intestine
what is the job of bile
neutralises the stomach acid and breaks down fats
where is bile produced and stored
produced in the liver, stored in gall bladder
what does bile do in the stomach
the hydrochloric acid in the stomach makes the pH too acidic for enzymes to work properly. Bile is an alkaline, it neutralises the acid
how does bile emulsify fat
it breaks it down into small droplets, this gives it a much bigger surface area for the lipase to work on, which makes digestion faster
what are products of digestion used for
build new carbohydrates, lipids and proteins. some glucose is used in respiration
