INVESTIGATING THE EFFECT OF TEMPRATURE ON THE ACTION OF AMYLASE ON STARCH

AIM: I am trying to find out how the temperature affects the action of amylase on starch.

BACKGROUND KNOWLEDGE:

Enzymes are composed of amino acids, they act as catalysts to regulate the speed of chemical reactions in living organisms. Hydrolytic enzymes speed up reactions; amylase is one of these. Enzymes regulate the speed of chemical reactions by building up or breaking down substances, this is done by the 'lock and key' sequence. All enzymes have their own specific shape- like all locks, like a lock it has a specific 'key' that fits into the specific substance, that is exclusive to its appropriate enzyme. Enzymes have an optimum temperature and pH to work in, when the temperature is too high for an enzyme it will become deformed and will cease to function, but if temperature is too low it will function but at a low rate to a point where again it will cease to function; until the heat has been regained.

Starch is a carbohydrate made up of a chain of glucose. Starch is an insoluble, complex molecule and is titled
