B9.3 Anaerobic Respiration

This lesson is the third lesson series of Unit 9 of the AQA specification. It introduces the topic by thinking about why why a marathon runner has to run a lot slower, and what would happen if they tried to run a marathon at sprint pace. Alternatively, students can complete a starter ‘Muscle contraction’ where they talk about why they are unable to stand on tiptoes for an extended period of time. This is followed by a recap of aerobic respiration. Students then support their understanding of anaerobic respiration by completing a written exercise, supported by textbook work and a video and a short practical. The idea of lactic acid and oxygen debt are then explored before describing using of anaerobic respiration in industry (e.g. food and beverage manufacturing). Lastly students have the option of completing as may of the three plenary activities. Exam questions are also available for extensions/ or homework. All mark schemes are also provided.
