have occurred when measuring the amount of foam produced from each reaction‚ which decreased the precision of the results. Due to reaction time when using a timer the exact rate of reaction of the catalase activity cannot be determined. The time the liver reacts with the solution varied with the sample of 3 for each temperature. Because the reaction initiates as soon as the reactants make contact catalase activity would be higher than the true value in the results. Another possible error is that the

with the intention of primarily affecting the liver. The liver is a major body organ that must function properly in order for the entire body to work. If the liver shuts down‚ the body can only live a couple of days. The liver is a storage place for iron‚ vitamins‚ and sugar that the body needs for energy. The liver also helps cleanse the body of waste products‚ poisons‚ and drugs that could potentially harm the body. When Hepatitis attacks the liver it affects the liver’s abilities to store iron

catalase? How does the activity of catalase compare in liver and other tissues? Hypothesis Part A: If the liver is placed in 2 ml of 3% hydrogen peroxide‚ then the result will be a high rate of reaction because catalase reacts with hydrogen peroxide to form hydrogen and oxygen. If pieces of potato‚ chicken‚ and apple are placed into 2 ml of hydrogen peroxide separately‚ then the chicken will have the highest reaction Part B: If the liver is placed in 2 ml of 3% hydrogen peroxide at room temperature

"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver" Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme‚ it fits into a depression on the surface of the enzyme molecule. This depression is called the
