What factors affect the activity of enzyme catalyse, on hydrogen peroxide?
Skill Area P
The problem
The problem that we are going to investigate will be what factors
affect the activity of enzyme catalyse, on hydrogen peroxide. The
factors we should investigate are
1. Temperature
2. Amount of enzyme
3. pH level
4. Amount of substrate (hydrogen peroxide)
Background knowledge
An enzyme exists in all living things. They are produced in all
living cells. In each cell there are several hundred enzymes, which
catalyse at a vast number of chemical reactions. Without enzymes the
reaction would be to slow and life would grind to a halt.
Enzymes dramatically increase the rate at which a reaction
occurs in living things without being used up or effecting the
reaction in any way, which enables it to be used up over and over
again.
An enzyme saves the need to change the temperature, pH level or
concentration to speed up the reaction which could harm the organism.
Enzymes are proteins, which is quite odd as they break and
digest proteins. There is only one type of enzyme which speed up the
breakdown of hydrogen peroxide into oxygen and water in your body.
Active liver cells in mammals produces a poisonous chemical
called hydrogen peroxide, which is very harmful to your liver. It
must be removed if liver cells are not to be harmed.
The enzyme catalyse breaks down hydrogen peroxide into water and
oxygen, which can be disposed of easily.
