of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can be describe as molecules

Review paper. Catalysts analysis for MSW pyrolysis and gasification Tursunov Obida‚ Khairuddin Md Isaa‚ Dr. Ong Soon Ana aSchool of Environmental Engineering‚ University Malaysia Perlis UniMAP‚ Arau 02600‚ Perlis‚ Malaysia Abstract MSW pyrolysis and gasification are the possible alternative to the direct use of fossil fuel energy. MSW‚ a CO2 neutral source of renewable fuel‚ can contribute to the demand for heat‚ electricity and synthesis gas (syngas). Nevertheless‚ there are inefficiencies in

withstand abnormal changes in pH without denaturing itself. Salivary Amylase is an enzyme that acts upon any polysaccharide that enters the mouth (mainly starch). However‚ it has a few other clinical uses. It is used for the diagnosis of acute pancreatitis‚ an inflammation of the pancreas‚ and other medical conditions regarding Amylase levels in the body. Amylase’s first discovery in 1831 led to new experiments about this enzyme. By separating pancreatic Amylase from Trypsin‚ they were able to realize that

Question One Description on what junket contains and how it works. “The dessert named junket is made by adding the enzyme Rennin to lukewarm milk. Rennin. also known as Chymosin or in its commercial form as Rennet‚ is found in the fourth stomach of cud-chewing animals‚ and is to be found in particularly high quantities in the fourth stomach of suckling calves. The enzyme curdles the milk by transforming caseinogen into

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature

of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the larger the effect of that specie’s concentration on the rate of the reaction. So for the chemical

Class divide has long been a catalyst for conflict within nations. History is littered with small groups of elites ruling over the masses. Time and time again‚ conflict occurs when the divide reaches a tipping point and the ruling elite bourgeois class and the proletariat masses must resort to violence in order to gain‚ or retain their control. A long history of stronger nations exploiting weaker nations has created a cycle in which a small minority controls most of a nations wealth‚ creating oligarchies
