2.34 describe the differences between aerobic and anaerobic respiration

Aerobic respiration – Respiration with oxygen, a multistep reaction catalysed by enzymes in the mitochondria

Anaerobic respiration – Respiration without oxygen. It’s a quick, instant burst of energy. This burst of energy if used on a long period of time could lead to buildup of lactic acid. This build up can lead to a high concentration of lactic acid in your muscles and can cause fatigue, muscular pains and cramps. This is why you continue to breathe hard after exercise – you’re repaying oxygen debt. (oxygen is required to oxidise to convert harmful lactic acid into harmless products – like water and CO2)
