Unformatted text preview: Reanna Echeverria 02/19/2011 Bio 100 lab: WESA Enzyme Function And Activity: pH Introduction: Hypothesis: The catalase activity in liver cells with work best at a pH at or around 8 because that is the pH level of the human body. Prediction: If the pH is basic, the liver cells with be denatured, if the pH is acidic, the liver cells with also be denatured, however, if the pH is at or around 8 catalase activity will occur. Background: “Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.” (Nishiura). “Extremely high or low pH recognition or an enzyme might become inactive....
