# Class 11 | Botany | Aerobic Respiration vs Anaerobic Respiration

The percentage of energy released during lactic acid and alcohol fermentation in comparison with aerobic respiration of one glucose molecule is here aerobic respiration anaerobic respiration both are different aerobic respiration takes place in the brains of oxygen.

Aerobic respiration takes place in the presence of oxygen whereas anaerobic respiration that takes place in absence of oxygen let us see what is the main difference.

In between aerobic respiration and anaerobic respiration aerobic respiration equation goes like c6 h12 o6 plus 602.

Give rise to 6 co2 plus 6 h2o and about 38 atp molecules are formed this is in case of aerobic respiration of glucose molecule if you see anaerobic respiration of the.

Same glucose molecule c6h12o6 that give three h2 in the absence of oxygen 2 co2 plus 2 c 2 h 5 o h that is ethyl alcohol plus just 2 atp molecules are formed this is anaerobic respiration.

So we surprised to know that the presence or absence of oxygen makes that much difference in the presence of oxygen 38 atp molecules are formed from same glucose molecule in the absence of oxygen just.

Two atp molecules are formed from same glucose molecule so organisms try to perform aerobic respiration instead of anaerobic respiration as they try to yield more amount of energy from the same glucose molecule.

If you see here compare that to atp molecules with 38 atp molecules that is if 38 atp molecules if we take it as equal to 100 percentage then 280p is equal to how much percentage that is.

2 by 38 into so 2 by 38 is equal to 0.0526 into 100 is equal to 5.26 percentage this is the amount of what we call.

Energy liberated during anaerobic respiration this is energy of anaerobic respiration so if you take that.

38 atp molecules are 100 percentage and anaerobic respiration is just 5.26 percentage the question here is that the percentage of energy released during lactic acid and alcohol fermentation in comparison with aerobic respiration of one glucose molecule is.

That is less than 7 percentage that is option 1.
