Biology AT1 on the affect of hydogen peroxide on the liver
took a long time with lots of research Well Presented
Aim: '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 …showed first 75 words of 557 total…

3. Add 10cm' of hydrogen peroxide to the liver. Replace the bung quickly so that no gas is lost.
4. After 10 seconds record the amount of water displaced in the burette. Record this amount on a table.
5. Repeat steps 1-4 heating the liver to 30'C, 40'C and 50'C.
6. Repeat steps 1-5 with liver weighting 1.4g cut in half, into quarters and ground up.
7. Remember to wear goggles and use all the safety procedures.
