An Investigation into the effect of ethanol on Enzyme Activity
It is common knowledge that too much alcohol can damage the liver, preventing it from efficiently filtering the blood, producing bile, detoxifying poisons and controlling fat levels in the body. A large amount of these functions are controlled, in part, by an enzyme named catalase. This can be found in mammal liver cells as well as other cells, in both instances it is responsible for the conversion of hydrogen peroxide into oxygen and water:
2H2O2 H2O + O2
Hydrogen peroxide may be present in humans as a result of the break down of fatty acids which also takes part in the liver (in other cells it is a result of aerobic respiration), as hydrogen peroxide is a powerful oxidising agent it is vital to maintain a controlled level, small amounts may actually be used in the liver to oxidise other harmful toxins such as alcohol. I intend to determine whether a large amount of alcohol will damage the catalase enzymes or conclude that liver damage that prevents adequate function is due to alcohol affecting other systems in the liver.
