The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

Art Report – Abstract Expressionism Abstract expressionism was first used in the Germany magazine Der Sturm in 1919‚ regarding as “German expressionism”. The term “abstract expressionism” was first applied to American art in 1946 and gained acceptance in the 1950s. It was mostly used in New York and San Francisco Bay area of California. Abstract Expressionism mainly comes from “Surrealism”‚ which represents spontaneous artwork. In combination‚ abstract expressionism has an image of being

ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme‚ the pH of the solution‚ the concentration of the enzyme‚ substrate and the product. Also‚ another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all‚ I have chosen to explain the effect of temperature and also the effect of inhibitors on enzyme activity

AIM The aim of this investigation is to explore the effect of different concentrations of bile salts on the time taken for the lipase enzyme to break down fat. BILE Bile is a brownish bitter alkaline fluid produced by the liver and made by the hepatocytes from water‚ bile salts‚ bile pigments cholesterol and phospholipids and stored in the gall bladder. Bile is directly connected with digestion. It is released sporadically into the small intestine (duodenum) which is part of the gut in order

INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical

A Study of Tourist Perception Towards Travel Risk Factors in Tourist Decision Making Anshul Garg Abstract People from different cultures tend to have different ways of making decisions‚ based on the emphasis they place on different phases of the decision making process. Studies have also suggested that people from divergent national cultures use different negotiation approaches‚ and they do so because their perceptions of the decision making situation are conditioned by the characteristics

Aesthetics of Abstract Expressionism Project Prepared for Donald McIntyre Professor‚ DeVry University Project Prepared by Colleen Mitchell Student‚ DeVry University June 7‚ 2009 Modernism is one of the cultural movements which took place in the nineteenth to the twentieth century. This movement was sure to draw attention to the artists’ work of art mainly because of the complexity of the artist’s creativity and breaking away from the more traditional works.

The Human Abstract/ A Poison Tree By Alex Jamani To analyze and compare William Blake’s poems “The Human Abstract” and “A Poison Tree”‚ it is necessary to understand not only his words‚ but human nature and the mind as a whole. We as people have many tendencies and susceptibilities to everything that happens in our daily lives; toward nature‚ emotions‚ friends‚ and enemies. Our reactions to these tendencies shape our emotions‚ and enable us to build feelings and expectations of others. In “A

Poster Abstract Postnatal depression PND in women after childbirth has been a major health issue for some time‚ this illness will affect at least one in seven women after giving birth. It is often undetected by the health care professionals and also been misunderstood out in the community. Sometimes PND can be misdiagnosed as baby blues. As for baby blues is when mothers are feeling miserable‚ weepy‚ tired and tense these types of feelings may occur during the first few days after a woman has
