"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

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

With the introduction of chemoembolization for the treatment of‚ primarily‚ liver tumors‚ a question emerges; which radiologic modality is better: chemoembolization or traditional radiation therapy? While both chemoembolization and traditional radiation therapy have their benefits and obstacles‚ will chemoembolization be more effective at treating liver cancer?

They merge into the portal vein‚ which then branches into smaller vessels and travels through the liver. If the vessels in the liver are blocked‚ it is hard for the blood to flow causing high pressure in

The yellow color of the eye in patients with scleral icterus can vary from a muddying to a bright yellow or an orange discoloration. scleral icterus does not cause any vision changes. Scleral icterus is not a disease in itself but a symptom of an underlying medical condition. When the underlying condition is treated‚ then the scleral icterus is also resolved. Causes: Bilirubin is a pigment that is excreted in bile and urine‚ and is processed by the liver. What occurs in
