Question

A common practice of competitive short-distance runners is to hyperventilate (breath rapidly and deeply) prior to a sprint. During the sprint, O2 cannot be transported to the muscles quickly enough to oxidize pyruvate, and metabolism in the muscles occurs anaerobically. a. What would happen to the pH of the blood during hyperventilation and why? b. Write out the equations for the most dynamic component of the blood buffering system. During a sprint, lactic acid builds up as a byproduct of anaerobic respiration? If the concentration of carbonic acid (pKa-6.37) in the blood is 1mM, what would be the change in physiological pH if 0.08mM lactic acid is produced. For this problem, assume lactic acid is a strong acid (it's . not really).

Explanation / Answer

A. During the hyperventilation the blood loses its carbon dioxide and there will be increase in the blood pH which is more alkaline.

At the hyperventilation condition we used to breathe heavily we take more amount of oxygen so there will be a deficiency in carbon dioxide in the blood so the pH of the blood rises.
