Question

The primary source of H+ released during exercise is lactic acid produced by the working muscle. Which of the following statements is/are CORRECT?

A. 3 ONLY                 1. Respiratory compensation refers to an increase in ventilation       

B. 2 & 3                          rate associated with the accumulation of lactic acid in the blood.

C. 1, 2, & 3                 2. The muscle buffering capacity is limited; therefore, extracellular

D. 1 & 3                           means of buffering H+ are of major importance.

E. 1 & 2                       3. The major extracellular H+ buffer is blood proteins.

please provide explination

Explanation / Answer

E. 1 & 2.

During exercise we breathe faster and shuttle more oxygen to muscles hence there is accumulation of lactic acid and there by there is increase in ventilation rate.

The increased lactate levels during exercise is reduced by acclimatization of H+ ions.
