When you do strenuous exercise, oxygen is used up rapidly. What substance is formed. a) pyruvic acid(pron: pie-ROO-vik) b) lactic acid c) glucose d) alcohol
option B. Generally, the glucose undergoes metabolism withinside the presence of oxygen to shape ATP(adenosine triphosphate) that is crucial for the muscle contraction however at some point of strenuous exercise, the frame can't meet the oxygen call for and the glucose undergoes metabolism withinside the absence of oxygen which ends withinside the formation and accumulation of lactic acid.Hence in the course of strenuous exercise,glucose is transformed into lactic acid.
