Horizontales
A large biological molecule made up of three fatty acids and one glycerol molecule.
A substance which binds to the active site of an enzyme.
These products are produced when proteins are broken down by protease (two words).
A large biological molecule made up of simple sugars.
A fluid that is made in the liver, stored in the gall bladder and released into the small intestine. It aids digestion by creating alkaline conditions in the small intestine and by emulsifying fats.
These products are produced when fats (lipids) are broken down by lipase (four words).
Solution used when testing for starch.
A type of digestive enzyme that catalyses the breakdown of proteins into amino acids. Found in the stomach and small intestine.
A digestive enzyme that catalyses the breakdown of starch into sugars. Found in the mouth (salivary glands) and small intestine.
A biochemical test to detect proteins in solution. a positive test for protein produces a purple colour.
Verticales
The colour observed if the test is negative when testing for sugars.
A type of digestive enzyme that catalyses the breakdown of lipids into fatty acids and glycerol. Found in the small intestine.
An organ in the mammalian digestive system which produces amylase (two words).
A protein that acts as a biological catalyst.
Reagent which is used when testing for simple sugars.
An organ (and gland) in the mammalian digestive system which produces protease and lipase.
Type of variable when something is changed for each experiment. In this case, investigating the rate of pH on enzyme activity.
