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

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

The Effects of Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH. BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which

Investigation on Effects of Different pH on Enzyme Activity How does the different pH buffers affect activity of potato enzyme/extract? Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each

Resistance to Change MGT/426 Resistance to Change One of the many attributes that contribute to the lack of a successful implementation of a change within an organization is the “resistance to change”. As with any form of resistance‚ resistance to change is something that can bring about a strong response. Many experts refer to the resistance to change as a cancer within the organization‚ and the main killer of progress and good-intentions. While change and resistance to change will be analyzed in

Title: A Research on SMRT’s (S’pore) resistance to change How resistance to change affects SMRT’s efficiency in the transport industry (i) To Research on the importance of Change (ii) To Investigate why change is resisted (iii) To Search for methods to reduce resistance To make this huge organisation tick‚ SMRT employs about 2‚700 staff (SMRT‚ 2012). This would mean to say that implementing a series of change into the organisation would be met with resistance. In the past years‚ SMRT trains have

AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones

The Effect of Starch on the Activity of Amylase with pH Variable Lab Report‚ Fall 2011 East Tennessee State University Department of Biological Sciences By: Shelby Brackett Date Performed: October 10‚ 2011 Lab Instructor: Joseph Kusi Biology 1111‚ Section 018 Abstract Enzymes are very important in chemical reactions. They are used to speed up the reaction taking place. They act by binding to a specific substrate and form an enzyme-substrate complex that may put stress on chemical bonds

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially
