so during exercise, your body respires anaerobically. the word equation for it is glucose-->lactic acid. So no carbon dioxide is made? I don't get that because when you breathe out surely you're breathing out carbon dioxide or something? Like you can't just be breathing out air. I hope that made sense! thanks

Hey so you don't get carbon dioxide as a product in anerobic respiration because there are no oxygen molucoles reacting to produce the carbon dioxide..
Remember carbon dioxide consists of carbon atoms and oxygen atoms . There are no oxygen atoms so you can get carbon dioxide
Hope that makes sense ???

Surely you aren't just respiring anaerobically though? There is some oxygen for aerobic respiration (producing the CO2), the anaerobic respiration just produces more energy than can be produced with the oxygen you have.

Not sure though, been a while since I crammed GCSE biology!

Ohhhh that makes sense. But like, what are you actually breathing OUT then? Surely then you don't even need to breathe? lol sorry if this question is really odd I just don't get it

Humans mainly do aerobic respiration. Humans only do anaerobic respiration when exercising when there is not enough oxygen getting into your lungs.

Lol it's ok . When you an doing anerobic respiraton during expertise you still breath as your body is still trying to get oxygen in to break down the lactive acid that's building up on your muscles
I think that's how it works . Its a bit technical.
