Investigating the Effect of Lipase Concentration on the Breakdown of Fat in Milk INTRODUCTION: Enzymes are proteins which can catalyse chemical reactions without changing themselves. The enzyme lipase breaks down the fat in dairy products such as full-cream milk for people who are lactose intolerant. Lipase acts on its specific substrate‚ lipids produces fatty acids. If enzyme concentration increases‚ random collisions between the substrates and active sites of enzyme increase due to the increasing

Science IA Rough Draft The Effect of Temperature on The Activity of The Enzyme Catalase Introductions: Enzmyes are proteins that catalyze chemical reactions. All living things have catalase present in them. Catalase is a common HYPERLINK "http://en.wikipedia.org/wiki/Enzyme" enzyme found in nearly all living organisms that are exposed to oxygen‚ where it HYPERLINK "http://en.wikipedia.org/wiki/Catalyst" catalyzes the decomposition of HYPERLINK "http://en.wikipedia.org/wiki/Hydrogen_peroxide"

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

How Environment Can Effect Enzymes Introduction: In a chemical reaction there sometimes can be a catalyst present known as an enzyme. An enzyme is a protein that speeds up a chemical reaction by lowering the amount of activation energy required to start the reaction. By lowering the activation energy‚ more of the substrate is able to participate in the reaction‚ speeding it up. Enzymes are substrate specific. The substrate is what the enzyme bonds to. That is to say that enzyme A will only react

EFFECTS OF CLIMATIC ELEMENTS ON LIVESTOCK PRODUCTION SALAMI‚ Saheed Ayodeji University of Ilorin‚ Ilorin‚ Nigeria. INTRODUCTION Climatic elements have direct effect on the system of animal production‚ body physiology and animal behaviour‚ feed supply and quality‚ proliferation of pests and parasites as well as preservation of animal products (Samson et al.‚ 2011) A number of climatic elements such as temperature‚ rainfall‚ humidity‚

Abstract Enzyme catalysis was observed in order to analyze how changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly‚ decreases‚ and levels off or completely stops‚ and can be further affected by environmental factors

Oil & Natural Gas Market Brief Study of the Oil & Gas Industry in India & Indonesia INDIA MARKET OIL SECTOR India was the fifth largest consumer of oil in the world during 2006 and 2007 (According to EIA estimates). According to Oil & Gas Journal (OGJ)‚ India had 5.6 billion barrels of proven oil reserves as of January 2007‚ the second-largest amount in the Asia-Pacific region (behind China). Much of India’s crude oil reserves are located off the western coast (Mumbai High) and in the northeast

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

Why are there so many different varieties of cheese when the production process is basically the same for all cheeses? Cheese comes in a wide variety of flavors‚ textures and styles‚ but the process for making all cheeses remains basically the same. All types of cheeses requires almost the same processes‚ but there are many different factors that influence how the finished product tastes‚ textures and smells. The climate of the area where the cheese making may influences the type of cheese
