A muscle tissue contains 2.5 mM lactic acid or lactate. Let's assume that the pH is 7. If you need other assumptions, state them.
a. If the ([NAD+]/[NADH]) = 1.0, what is the concentration of pyruvate at equilibrium?
b. If the glucose concentration in the muscle tissue is 3.5 mM at pH 7, what ratio of ([ATP]/[ADP]) is maintained in the muscle tissue at equilibrium?
c. Why did we need to know the ratio of (NAD+]/[NADH] to answer question 1a?
