An Investigation Into The Rate of Reaction of The Catalase Enzyme
Introduction:
In this experiment I will attempt to investigate the factors that
effect the rate of reaction of the catalyse enzyme.
Catalyse is an enzyme found in food such as potato and liver. It is
used for removing hydrogen peroxide because of the shape of the
hydrogen peroxide molecule; this type of reaction is when a molecule
Is broken down into smaller pieces called catabolic reaction.
Enzymes are proteins e.g. catalyse. They are made in cells. A catalyst
is something that speeds up a reaction.
One molecule can usually be used many times.
All enzymes work at different pHs because they have different jobs to
do but you cant use a ph which isn't suitable for that particular
enzyme which you are using, other wise the enzyme will de nature.
Enzymes also react with tempreture but like the ph the temperature
cant be unsuitable to the enzyme other wise it will de nature or slow
down the enzymes which would make it very difficult to obtain accurate
and reliable results.
A carbohydrase enzyme is different to a catalyse enzyme and other
enzymes because enzymes have different patterns (shape). Enzymes are
like keys to different substrates like e.g. fat, sugar and the
substrates are like keyholes.

As you see from the preliminary results there where a lot of problems
along the way but this is only to help me set out the proper results
