1. The reaction above is important in muscle cells during exercise to regenerate NAD+ needed for glycolysis. The equilibrium constant = K = 8.8 x 103 for the reaction above. The reaction is catalyzed by lactate dehydrogenase, (for your information, not relevant for the problem). a. Is G0 for the reaction positive or negative? b. Which direction does the reaction proceed (forwards or backwards)? c. If a lot of lactate is added to the reaction, which direction will it help drive the reaction (forward or backwards)?
