This hypothesis should have been proven true with the experiment‚ but due to some error the iced liver had the greatest rate of O2 production. Things that could have affected the rate of reaction could include: the iced liver being left in room temperature conditions too long before beginning the experiment‚ accidental added motion from moving the test tube during the reaction causing molecular collision to occur

esophageal varices is a disease process it is mainly caused by other conditions. Most notably are liver cirrhosis (caused by either alcohol abuse or hepatitis infection) and deep vein thrombosis of the mesenteric or portal veins. Because the only real symptom of esophageal varices is bleeding it is often only diagnosed after an episode of bleeding or as part of a work up for another condition such a liver cirrhosis. due to late diagnosis and the asymptomatic nature of this illness it can be fatal.

Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

and‚ after biochemical alteration in the liver‚ becomes "conjugated" (or direct) bilirubin. Conjugated bilirubin is a major part of bile. Bile is a substance that breaks down fats‚ and is often yellow or brown in color. It is released into the small intestine by the gallbladder when it’s needed to break down fats that are being digested. When an abnormally high number of red blood cells are broken down‚ bilirubin can build up quickly in the body. Liver disease can also cause bilirubin levels to

the inflammation of the liver and hepatitis B is a specific type of this infectious disease caused by the hepatitis B virus (HBV). The symptoms of HBV infection vary from person to person. Many people with HBV infection don’t develop any symptoms‚ especially when they are young‚ and most patients with chronic HBV infection don’t develop any symptoms until late stage. However‚ HBV can damage the hepatocyte (liver cell) and cause liver damage and cirrhosis (scarring of the liver). HBV can cause both

10 hours after eating the mushrooms Caesar seemed well. After 15 hours his liver cells stopped functioning. He then showed signs of nausea‚ diarrhea‚ and confusion because his liver could no longer filter and remove waste from the blood. He died two days later from liver failure. 1. What makes transcription important? 2. What is the purpose of proteins? 3. How would a substance that affects transcription make the liver to stop functioning? 4. Why did it take Caesar two days to die? Claudius

Procedures: Place 1 ml of the 3% hydrogen peroxide solution into a clean 10ml graduated cylinder. Using forceps and sharp knife/scalpel cut 0.1g of chicken liver (this is approximately half the size of a 10c coin) and add it to the measuring cylinder Label measuring cylinder 1 – (temperature of chicken liver) Push the piece of liver into the hydrogen peroxide with a stirring rod. Observe what happens. Leave the reaction for 4 minutes and then measure how high the bubbles rose. Record the

a shipment of pork livers. Here’s how the disagreement came about. The American exporter was contracted to ship “30‚000lbs‚ of freshly frozen U.S. pork levers‚ customary merchantable quality‚ and first rate brands.” The shipment had been prepared to meet the exacting standards of the American market‚ so the exporter expected the transaction to be completed without any problem. But when the livers arrived in Germany‚ the purchaser raised an objection: “We ordered pork livers of customary merchantable

change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will decrease
