Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit which allows the reaction to occur and a new product to be

environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using a chromogenic

Rates of Chemical Reaction II Pre-Lab Summary: First we will set up the experiment as shown in Figure 2‚ and then we will fill the trough with room temperature water and record the temperature and we will also add the room temperature water to the buret until it is about 10ml from the top. If there are no leaks in the apparatus‚ we will add 10ml of KI to 15ml of distilled water in a 125ml flask. We will swirl the flask so that it achieves room temperature‚ then we will add 5ml of H2O2 and quickly

In this paper I will discuss and analyze some of these trends such as: global‚ economic forces and its impact‚ organizational structure‚ culture‚ process and general management. Nayar’s case study‚ shows that HCL Technologies was becoming a company with growth‚ diversity and to show organizational structure. According to Hickman (2010) global segment happen when “there is an increasing trend for firms to expand their operations and market reach beyond the borders

an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the product of the reaction between sodium thisoulphate and hydrochloric acid (HCL) is precipitates of

Purpose: To determine the effect of various factors on the rate of reaction between an enzyme andits substrate‚ and also to determine the optimal ranges under which the enzyme activity ismaximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme willincrease until it reaches optimum pH range (pH 7) because the enzyme is less denaturedwhen it reaches the preferred pH level
