      In the same way your body gets a stitch after PE! In low oxygen conditions (anaerobic respiration) the body uses an electron carrier molecule to break down sugar. It’s not as efficient and so aerobic respiration (using oxygen) is so much better.

      I seemed to recall something about this from GCSE biology but would have had to google it to give you an accurate answer! Just like aerobic respiration, Paul’s explanation is much better!
