    BCHE 5180 / 6180 FINAL EXAM | Graded A

  • BCHE 5180 / 6180 FINAL EXAM | Graded A.Based on what you have learned about the functioning of enzymes and proteins, explain why the pH in the cell has to be buffered. A large group of enzymes show a pH optimum for their activity. This value is normally close to the pH in the cell. When the pH in the cell changes this can lead to a protonation or deprotonation of an amino acid that is important for the enzymatic activity. As a result the activity will decrease. Upon large changes in pH add...
