    Temperature and pH will both effect and change the active site of an enzyme. Denaturing‚ the changing of the shape of an enzyme‚ will occur if a big enough change in temperature and pH to go away from that enzyme’s optimal conditions. Each enzyme has optimal conditions which is the best temperature and pH for that enzyme to function. When temperature and pH move away from those conditions the enzyme could slow down its rate of activity

    Monica Mahmoudi 02072798 Bandaruk Mon-Wed 12:45 PH Balance in the Human Body As we all know every solution is either acid or alkaline. Alkaline is often called base. These solutions can be anything from body fluids‚ to fruits‚ vegetables‚ seawater‚ beverages you name it. Acid and alkaline is measured in pH. It starts as low as zero being very acidic and works its way up to fourteen being the most basic. The pH of our stomach is 2‚ obviously to digest food‚ wine is 3.5‚water is 7(neutral)‚ arterial

    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

    Testing the pH of Common Household Substances Lab Background Information: The pH scale is used to determine the acidity or basicity level of liquid solutions. If a solution scores a pH level of 1-6 it is an acidic solution‚ 1 being the most acidic and 6 being the least acidic. If a solution rates a pH level of 7 it is a neutral solution‚ meaning it is neither an acidic nor a basic solution. Lastly‚ if a solution is 8-14 on the pH scale it is a basic solution‚ 8 being the least basic and 14 being

    Observing Enzyme Activity Purpose: The purpose of this experiment was to test whether the pH affected the enzyme reaction rate. Hypothesis: If the enzyme is in a basic solution‚ then it will react faster because the enzyme (catalase) reacts better in basic solutions. Materials: 10 potato cubes (1 cm3) -Pipet Baking soda solution -50 ml glass beaker Bleach Water Lemon juice Vinegar 5 glass test tubes Drying rack Timer Graduated cylinder Hydrogen peroxide Procedure:

    Factors affecting Enzyme Activity: The effect of pH on enzyme activity Background Knowledge: An enzyme is a biological catalyst – which speeds up the reaction rate‚ without itself getting altered. Enzymes are proteins with long polypeptide chains that are folded up into three – dimensional shapes. An enzyme acts on a substrate to convert the substrate into a product useful for the organism.The active site is a special region on the surface of the enzyme where the substrate binds to the enzyme.
