the digestive system Flashcards
carbohydrates become
sugars eg glucose
the enzyme for carbohydrates is
carbohydrase
bile is produced in
the liver
bile is stored in
the gall bladder
bile contains
sodium hydrogencarbonate (alkali)
bile produces
the optimum pH for pancreatic enzymes
emulsification is
the breaking up of a large drop of fat into tiny droplets of lipid meaning they have a higher sa
digestion means
to break the food down into smaller soluble molecules
chemicals in the body that speed up digestion are called
enzymes
digested food is absorbed into the blood in the
small intestine
peristalsis is
a word used to describe the muscular contractions in the oesophagus that push food into the stomach
how long is the small intestine
7m
food is …… down by your teeth
this action is called …….. digestion
broken
physical
it is then followed by …….. digestion in the …….
chemical
stomach
vitamins and minerals do not need digesting because
they are small enough to be absorbed to start with
digestion of carbohydrates happens in
mouth and small intestine
enzyme for protein
protease
enzyme for fat
lipase
protein product of digestion
amino acids
fat products of digestion
fatty acids and glycerol
protein takes place in the
small intestine and stomach
fat digestion takes place in
the small intestine
test for starch
iodine solution
orange ➡️ blue/black
test for glucose
Benedicts solution
blue to orange red precipitate
test for protein
biuret solution
pale blue ➡️ pale purple
test for lipid
ethanol
colourless to milky white suspension
