The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

The rate of a chemical reaction is the measure of change in concentration of the reactants of the change in concentration of the products per time. The rate of a chemical reaction is influenced by the concentration of the reactants‚ temperature‚ and the presence or absence of a catalyst. Through finding the time and concentrations of the reactants‚ it is possible to find the rate of reaction and k. To perform this experiment‚ you need two erlenmeyer flasks‚a timer‚ a LabQuest with a temperature

world classlevel is not an easy task and it is a challenge to Malaysia.Currently‚ unemployment among the graduates becomes an issue‚ not only in Malaysia but also around theworld. The Department of Statistics Malaysia (2011) found that the unemployment rate in Malaysia hadincreased from 3.2 % in 2007 to 3.7% in 2009. The Minister of Human Resources‚ Fong Chan Onn‚ stated thatthe National Economic Action Council with the collaboration of the Department of Human Manpower hadconducted a census in 2005 and

Anya Sealy High Crime Rate We often hear about the high crime rate on television‚ radio or even newspaper. We hear about Politicians making promises to decrease the crime yet it has still continued to rise. I often ask myself‚ what are the root causes of committing these crimes‚ why do people do what they do? Politicians‚ during there rallies‚ hype up the crowds and make promises to do positive things and get as much support from the citizens as possible‚ leaving the nation with high

added more literates in rural India from 58.7% in 2001 to 68.91% in 2011‚ the job market hasn’t kept pace with the growing demands of job seekers from villages. The bigger cause for concern according to the labour ministry data is: the unemployment rate among rural educated youths is higher as compared to their urban counterparts. It stands at 13.9% for rural areas against 7.6% in urban areas. The ministry data‚ released on July 18 this year confirms worst fears of expanding education sector not

Purpose: The purpose of the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister

Biology coursework How does the temperature affect the rate of reaction? Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is
