milk Introduction Enzymes are globular protein‚ responsible for most of the chemical activities of living organisms. They are made up of long chains of amino acids containing carbon‚ hydrogen‚ oxygen and nitrogen (Gunsch‚ 2012). The role of enzyme is to act as catalysts‚ substances that speed up chemical reactions without being chemically altered during the process. The speeding up of chemical reactions is done by lowering the activation energy required to start a reaction. Enzymes are specific in

Catalase Lab Purpose: To observe the effects of hydrogen peroxide on living tissue and non-living materials‚ showing the presence or absence of catalase as observed by the presences of bubbles. Hypothesis: If we pour H2O2 on certain substances‚ the catalase will break down and bubbles will appear at the surface. Data table: Name | Time | Observation | Raw Potato | 1 min. 30 sec. | Slow reaction‚ barley any bubbles. | Raw Liver | 5 min. 30 sec. | Extremely fast reaction‚ very foamy‚ Big

Liver is one of the most important organs in human body‚ it helps in fighting infections‚ metabolizing drugs by producing enzymes‚ and synthesizing proteins like‚ albumin. Liver failure happens When the liver cannot adequately functions and it is life threatening condition if it’s not managed immediately‚ it might cause some complications‚ like cirrhosis‚ hepatitis and multi-organ damage.(1)Liver transplant might be a lifesaving solution with liver failure‚ unfortunately liver transplant have its

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

In this enzyme lab‚ (insert creative name)‚ the enzyme catalase was observed under varying conditions in order to interpret what prohibits and inhibits the functioning of certain enzymes in chemical reactions. Enzymes aid in chemical reactions by speeding up the time it takes for the reaction to occur‚ without getting “used up” throughout the process. Catalase‚ the specific enzyme used in this lab‚ is a protein abundant in the liver and red blood cells. It enhances the breakdown of hydrogen peroxide

Cirrhosis of the Liver Cirrhosis of the Liver: Causes‚ Detection and Prevention University of Phoenix- Online Campus Cirrhosis of the Liver is a horrible disease that takes the lives of many people every year. There are many causes‚ symptoms‚ ways to diagnose and treatments that surround this disease as well as many ways that this fatal disease can be prevented. The liver is a key organ when it comes to making the body function properly (National Digestive Diseases Information Clearinghouse

HL -Functions of the Liver Essay The liver receives its blood from two main sources; the hepatic artery and the hepatic portal vein. The hepatic artery transports oxygenated blood from the left side of the heart through the aorta to the liver. The deoxygenated blood from the liver is drained back out through the hepatic vein which returns it to the vena cava. The hepatic portal vein carries nutrient rich blood from the small intestine to the liver. Its blood however‚ is

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

Liver Transplant Surgery Risks and Benefits By; Daniel Allred January 5‚2010 7th Grade Science Core 2 Mr. Wright Organ transplants are some of the hardest surgeries that doctors can do. They require many trained personnel‚ time‚ and complicated procedures. Liver transplants are among the most difficult organ transplants that can be done. There are also many risks involved with the surgery and patients must face all of them in order to come out with a new and working liver

Effects of pH on the Function of Enzymes Rena Mototani Glen Rock High School Advanced Biology 2014-2015 Effects of pH on the Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The
