    Lab #6: pH Effects and Enzyme Concentration on Catecholase Activity Abstract: This experiment examined the effect on how the changes in pH balance of potato juice affected the enzyme activity‚ structural stability and solubility. Introduction: Enzymes are macromolecules that allow chemical reactions to occur. They function as biological catalysts. A catalyst is a substance that is involved in‚ but not changed by or consumed in‚ a chemical reaction. The amount of energy required for a reaction

    the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less effective

    Investigating the Enzymatic Activity of Catecholase through Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration University of Alabama at Birmingham Burgess‚ B.N. Introduction: Background Enzymes are macromolecules that act as catalysts in living organisms by speeding up chemical reactions without being changed or destroyed by the reaction (Campbell and Reece‚ 2008). Enzymes are able to speed up the rate of a chemical reaction by decreasing the activation energy during the reaction

    This experiment shows the effects of changing the pH level has on Catalase. As predicted‚ the farther away the pH levels got from the optimum pH (7.2)‚ the lower the reaction rate. At a pH of 7.2‚ the foam of the reaction measures 6cm. At a ph of 3 it measures 2.5 cm‚ at a pH of 5 it measures 2.75 cm‚ at ph 9 it measures 2.3 and at 11cm it measures 2cm. pH measures the hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result

    Armadillium vulgare taxis response to different pH levels. Abstract The terrestrial isopod‚ Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions‚ it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such‚ behavioural and physiological

    lab is to determine the pH level of common household products. Introduction Liquids are either acidic‚ basic‚ or neutral. We are able to figure out which one it is based on properties‚ along with the pH. Acids taste sour‚ and bases taste bitter. Using the pH scale‚ you are able to know how strong of an acid or base a liquid is. High concentration of [H+] ions means that the liquid has a low pH. Therefore a liquid with a low concentration of [H+] would have a high pH. A pH of less than 7 represents

    The effects of pH on mung beans Gloria Cheng Winsy Cheung Lily Wong Christine Yen January 15‚ 1998 Abstract This experiment explores how different pH environments affect the growth of mung beans. The mung beans were grown in water with various pH levels‚ consisted of pH levels 5‚ 6‚ 7‚ 8‚ and 9. A replicated design was used consisting of 3 runs for each pH level. The following results are listed in order of pH levels allowing most growth to least growth of the mung beans: 7‚ 8‚ 6‚ 5‚ and 9. These

    The Effect of pH on a Food Preservative September 18‚ 2012 Objective: To study the affect of pH on a food preservative. Chemical Equation: C6H5COONa + HCL ------ C6H5COOH + NaCl Procedure: This experiment was started with a clear solution of sodium benzoate and HCl was added to it‚ ultimately producing benzoic acid. First‚ .3395 g of sodium benzoate was weighed‚ then it was dissolved in water‚ causing it to disassociate into ions. Next‚ 3M of HCl were added drop wise to the solution

    Title : THE EFFECT OF PH ON THE ACTIVITY OF CATALASE Aim : To study the effect of pH on the activity of catalase. Introduction : Catalase‚ an enzyme found in many different tissues‚ catalyses the breakdown of hydrogen peroxide into water and oxygen. 2 H202 → 2H20 + O2 Hydrogen peroxide is a toxic substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by finding the rate of oxygen release from hydrogen peroxide

    Research Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. In the
