AQA GCSE PE: Aerobic Vs Anaerobic Respiration | How To Pass GCSE PE | AQA Paper 1 | GCSE Biology

This video seeks to outline the terms aerobic and anaerobic respiration. It is essential that YOU understand the definitions for each of these in preparation for your GCSE PE (9-1) paper 1 and biology examinations.

In addition to this, you need to understand the equations for both aerobic and anaerobic respiration. Furthermore, you need to be able to associate these terms with appropriate sporting examples highlighting the changes in intensity and duration, for example: highlighting that marathon running is predominantly an aerobic based activity as it is low intensity and takes place over a long period of time. However, there are still specific moments during a marathon where anaerobic respiration occurs. You need to understand why this is using a range of scenarios to support your response. It is also worth mentioning that this is applicable to many sports where the intensity frequently changes.

In association with this topic you also need to understand the term Excess Post-Exercise Oxygen Consumption (EPOC). This refers to excessive breathing and the consumption of large volumes of oxygen following anaerobic activity (where oxygen is absent). This therefore enables a performer to repay oxygen debt.
