Aerobic respiration uses oxygen to change glucose into carbon dioxide and water, producing energy.

Vigorous exercise requires anaerobic respiration. it doesnt require aerobic respiration because the blood wont be able to reach your muscle calls fast enough to deliver the oxygen they need.

A burst event (sudden vigorous activity). the energy comes from breaking down glucose into a chemial called lactic acid:

glucose ----> lactic acid (+ some energy)

Respiration does not use oxygen to react with the glucose

disadvantages of anaerobic respiration:

-produces much less energy than aerobic respiration

-when lactic acid builds up int he bloodstream, it causes muscle cramp.

once burst event is over, lactic acid needs to be removed, it breaks down into carbon dioxide and water, using aerobic
