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

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

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

It is hypothesized that the raw food will provide a higher rate of reaction than the cooked food will as the cooked food would have a higher chance of having denatured enzymes in comparison to the raw food.

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

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

Matt Feldman Mr. Mosher AP Bio 12/6/2012 The Metabolism of Alcohol This article describes the process the liver undergoes to breakdown the alcohol in your blood stream. Also it discusses the consequences of heavy drinking and the damage it causes to your body. The only cells in our body that can metabolize ethanol are in our liver. In the cells NAD+ oxidizes the ethanol to acetic acid‚ which generates an excess amount of NADH‚ which gives its electrons to the ETC. Then Oxidative phosphorylation

We observed its sensitivity to touch on different parts of its body‚ its sensitivity to talcum powder‚ its reaction to a small piece of liver‚ and its sensitivity to light. Introduction: The problem we are investigating is how sensitive it is to touch on different parts of its body‚ its sensitivity to talcum powder‚ its reaction to a small piece of liver‚ and its sensitivity to light. My hypothesis states that the planarian will be sensitive to touch on its face due to the fact that that’s

lipgenesis‚ cholesterogenesis‚ or ketogenesis o Not Glucogenic 3. What do amino acids and fatty acids produce during gluconeogenesis? Amino acids and fatty acids are oxidized to generate NADH & ATP needed for gluconeogenesis (b/c when liver is producing glucose‚ it cannot synthesize lipids and proteins at the same time) 4. What is produced during hepatic lipogenesis? Glucose must be used to produce NADPH and ATP necessary for the conversion of acetyl CoA to fatty acids 5
