Question

why does a runner breathe hard for a few minutes after finishing a race? the runners cells need oxygen to make lactic acid. the runners cells continue the fermentation process. the runners cells are making up for the oxygen deficit. the runners cells cannot perform glycolysis. schoology quiz - photosynthesis and cellular respiration

Explanation:

During intense exercise like running a race, the body's oxygen demand exceeds the supply. After the race, the runner's cells need to make up for the oxygen deficit incurred during anaerobic respiration (such as lactic - acid fermentation). The body breathes hard to take in more oxygen to convert lactic acid back to pyruvate and complete aerobic respiration processes to restore normal physiological states.

Answer:

The runner's cells are making up for the oxygen deficit.
