BCHE 5180/6180

BCHE 5180/6180 Exam Final. 100% Give the general Henderson-Hasselbalch equation and sketch the plot it describes (pH against amount of NaOH added to a weak acid). On your curve label the pKa for the weak acid, and indicate the region in which the buffering capacity of the system is greatest. [ A ] pH  pKa  log [HA] The inflection point, which occurs when the weak acid has been exactly one half titrated with NaOH, occurs at a pH equal to the pKa of the weak acid. The r...

BCHE 5180/6180: Spring Final (Graded A+) 1 3 points 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 chan...
