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

effect of pH on amylase activity This practical allows you to: * discover how pH affects the rate of an enzyme controlled reaction * evaluate the experimental procedure Procedure SAFETY: Follow your teacher’s instructions for handling the solutions. Wear eye protection when handling the iodine solution. Investigation * Place single drops of iodine solution in rows on the tile. * Label a test tube with the pH to be tested. * Use the syringe to place 2 cm3 of amylase into the

Effect of pH on Enzyme Activity Athenaa Jeyachandran Mr.Menes Course Code January 21st‚ 2013 The Effect on Enzyme Activity Due to Temperatures Purpose: The purpose of this lab experiment is to examine how different temperatures affect enzyme activity using hydrogen peroxide. Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes

studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure of the

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

bounded substrate. Amylase enzyme‚ just like any other enzyme‚ has an optimum PH and temperature range in which it is most active‚ and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2) the environmental factors that can affect the enzymatic activity. The hypothesis‚ in relation to the enzymatic activity by variables such as the substrate concentrations‚ temperature‚ PH and chemical interactions

What do you want us to bring you back?" Eric thought about it a moment‚ and responded in his low‚ heavy voice. "I’m not hungry right now. Go ahead." "You really should eat!" she yelled back. He didn’t respond. Instead‚ he went into his room‚ mirror in hand. Eric had long been obsessed with the paranormal‚ reading books of ghosts

Introduction Have you ever bit into a nice big juicy bacon double cheeseburger and your mouth began to salivate before the food has entered your mouth? The reason why you salivate is because your body wants to release an enzyme called amylase. Amylase is the enzyme found in your saliva. The purpose of this enzyme is to help in the digestion process (McD‚ 2002). Enzymes are biological catalyst that help speed up the reaction by lowering the activation energy. These enzymes allow your food to be digested
