Candace S. Randolph MISEP Cohort 2 Chemistry 512 Enzyme Catalysis Lab Report Pre-lab Questions: 1. Write a balanced chemical equation with state symbols for the reaction catalyzed by peroxidase. 2H2O2 2H2O + O2 (4H1 4O) (4H + 2O + 2O) 2. What is the substrate(s) of this reaction? What is the catalyst? Substrate = H2O2 hydrogen peroxide Catalyst = peroxide 3. At what approximate temperature do enzymes normally operate in the body of a warm-blooded animal? Would your answer change if the enzyme

experiment demonstrates that the catalase enzyme breaks down the hydrogen peroxide due to its harmful toxicity to the liver. In section A‚ the effect surface area has on the enzyme was tested. The results have proven that as the surface area increases‚ the reaction rate of the enzyme also increases. To illustrate‚ when the liver was ground‚ the bubbles from the reaction reached a maximum height of 150mm in five seconds less than the unground liver which merely reached a maximum height of 120mm. This is due

The study shows it is clear that although the Study-Study condition improves a student`s cognitive thinking and enhances a person to think rationally. The Study-Test method emphasizes how students will perform affectively on tests. Which teaches them how to test themselves independently through reading and studying. How it refreshes and develop their data analysis

Effects of Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme

“Liver transplant ethics: Should alcoholics be sober first? Toronto woman whose husband died in 2010 plans to launch charter challenge”. CBC News. 28 January 2015 This story appeared on the CBC news website‚ some of the questions and points this article raises are: • Should alcoholics be required to abstain from drinking for six months before they are eligible for a liver transplant in Ontario? • Does the six-month abstinence contradict the charter and Canadians’ right to universal access to

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

different possibilities of side effects. Antibiotics work by finding something in the pathogen that is different in the host cell and attacks it to stop the pathogen from reproducing and causing more harm. The side effects can range from loss of hearing all the way to discoloration of the teeth. Some may take these drugs and have no side effects at all except to obtain better health. While others may no receive any good from the medication and have horrible side effects. The mode of action also has

The purpose of this lab is to identify the physical and chemical properties of four liquids: acetone‚ vinegar‚ hydrogen peroxide‚ and oil. By using our knowledge about the four liquids we needed to identify the components of an unknown mixture. Theoretical Background The liquids commonly found around the house such as acetone‚ vinegar‚ hydrogen peroxide‚ and oil was tested to identify the physical and chemical properties of these liquids. Acetone usually used as nail polish remover dissolves plastic
