Lactic acid is a common by-product of cellular respiration and is often said to cause the "burn" associated with strenuous activity. A 25.0 mL sample of 0.109 M lactic acid (HC3H5O3,

pKa = 3.86)

is titrated with 0.109 M NaOH solution. (Assume that all solutions are at 25°C.)

(a)

Calculate the pH after the addition of the following amounts of NaOH.

20.0 mL
24.0 mL
24.5 mL
24.9 mL
25.0 mL
25.1 mL
26.0 mL
28.0 mL

Some explanations of glycolysis, lactic acid fermentation and aerobic cellular respiration seem to indicate that your cells SWITCH between the two options to finish glycolysis: lactic acid fermentation OR cellular respiration. This is not the case! Your cells do not choose EITHER lactic acid fermentation OR aerobic cellular respiration In the above situation, what will happen to glycolysis rates that move forward to lactic acid fermentation? Why?
