it is a process in which cell which use oxygen break down nutrients to give energy

it is the most efficient process as it gives most amount of energy

it is a very slow process as glucose needs to get oxidised for energy to get released and that happens in steps

the glucose molecules get oxidized hence releasing 2, three carbon molecules which release energy. then the three carbon molecules break to carbon dioxide releasing more energy

occurs when the supply of oxygen is less than the amount of oxygen our body needs

this process does not last very long as the lactic acid causes cramps

the heart rate remains high so it is able to remove excess lactic acid to kidneys. where rapid and deeper breathing rate ensures that there is a lot of oxygen which is required to break down lactic acid to carbon dioxide and water.

anaerobic respiration produces an oxygen debt. This is the amount of oxygen needed to oxidize lactic acid to carbon dioxide and water. The existence of an oxygen debt explains why we continue to breathe deeply and quickly for a while after exercise.

in brewing industries: yeast along with sugar into fermentation sugar is the substrate for aerobic respiration while yeast produces ethanol and carbon dioxide. carbon dioxide is allowed to escape while ethanol is packaged
