Biology questions? Anyone know the answer please. Cellular respiration.?

How does knowing the amount of pyruvic acid help determine the rate of glycolysis?

    It doesn't unless you also know the rate of pyruvic acid being converted into something else or exported or used.

    This is because glycolysis produces pyruvate as the first transitional step between glycolysis and the Citric Acid Cycle (aerobic) or lactic acid (anaerobic) tracks.

      But just measuring pyruvate levels does not tell anything about RATE of glycolysis.  Let's say you measure an increase--does that mean more is being produced, or less is being used up by downstream reactions?  You can't tell just by measuring its levels.
