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

Catalase Lab Introduction: Catalase is an enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism:

and spread to other organs. This process is referred to as metastasis. Metastases are the major cause of death from cancer. Key facts: Cancers figure among the leading causes of death worldwide‚ accounting for 8.2 million deaths in 2012 . Lung‚ liver‚ stomach‚ colorectal and breast cancers cause the most cancer deaths each year. The most frequent types of cancer differ between men and women. About 30% of cancer deaths are due to the five leading behavioral and dietary risks: high body mass index

highly trained cyclists and their livers. For the experiment‚ Swiss and British researchers directed the cyclists‚ all men‚ to ride to exhaustion on several different occasions. After each ride‚ they swallowed drinks sweetened with fructose or glucose‚ another simple sugar often identified as dextrose on ingredient labels. (Some also drank a milk-sugar sweetener.)

research paper is about Hepatitis C (HCV) causes inflammation of the liver and can cause liver damage foremost to cirrhosis. Irregularly‚ liver cancer may grow. First called non-A and non-B hepatitis‚ hepatitis C (HCV) was discovered in the early 1970’s‚ but it was not until 1989 that testing for particular antibodies to the virus initiated. Each year‚ 16‚000 Americans contract hepatitis C‚ which is a more common cause of prolonged liver disease than hepatitis B. roughly guessed the rate as high as 80%

A common enzyme that we have is catalase‚ which breaks down hydrogen peroxide into the products water and oxygen. To observe this catalase activity I used small amounts of liver samples slightly smaller than the size of a pea to see the reaction when hydrogen peroxide is added to it. In this experiment I exposed the liver samples in three different temperature environments: 3°c‚ 22°c‚ and 75°c. I wanted to measure how much water and oxygen is produced in each environment by measuring the visible

Simple Experiments on the Enzyme Catalase Aim: The aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Background information Catalase is an enzyme which is found in all living organisms. This enzyme catalases the decomposition of hydrogen peroxide into water and oxygen. Cells continually produce a poisonous by-product of metabolising‚ called hydrogen peroxide. This

Catalase Experiment Research Question: How does the weight of a piece of liver (0.4g‚ 0.8g‚ 1.2g and 1.6g in this case) affect the amount of gas created after 2 minutes when combined with hydrogen peroxide? Aim: To see find out how the amount of catalase correlates with the amount of gas created when in combination with hydrogen peroxide. Materials: 15g of liver 25 ml of hydrogen peroxide 1 scale 1 bucket 1 100ml graduated cylinder 1 250ml flask with bung 1 50cm tube (able to fix onto top of flask)
