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.

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

During this experiment the change in pH of Citric acids is measured from start to equilibrium in mL. This experiment was tested by titration it had two separate trials. Through observations it was shown that the more concentrated acids needed more drops of NaOH to reach its equilibrium then the less concentrated acids. Introduction Sodium Hydroxide (NaOH) is a strong base and when it is titrated with a strong acid the equivalence point will be expected to be a pH of 7 (wyzant.com‚ Feb. 12). NaOH
