KS3 Biology - Anaerobic Respiration - Activate2: 2.6 (+3.1) - AQA Activate 9.3.2 Challenge opportunities throughout Lesson starts with comparison of 2 types of athletes - one doing aerobic respiration and the other doing anaerobic. Aerobic respiration equation is recalled Anaerobic respiration equation is given Statement as to why anaerobic respiration releases less energy Oxygen debt is defined Equation also given for oxygen debt (lactic acid +O2 --> CO2 + H2O) Anaerobic respiration in plants and yeast - equation and comparison to anaerobic respiration in animals 6 mark question on comparing aerobic and anaerobic respiration Plenary which relates oxygen debt to shortness of breath following exercise Many answers animate onto screen to allow opportunity of peer/self assess See the lesson taught here: https://youtu.be/_nltNBZnOxE Also convenient for students who may have missed the lesson.

KS3 Biology - Aerobic Respiration - Activate2: 2.5 - AQA Activate 9.3.1 Lesson covers: Recap of the components of the atmosphere and that percentage of oxygen in the exhaled breath is lower - this leads into what oxygen could be used for. Photosynthesis equation is recalled and aerobic respiration is defined, as well as the terms endothermic and exothermic reactions - assigning these terms to photosynthesis and aerobic respiration respectively. Three specialised cell types are considered - sperm cell, muscle cell, and root hair cell - all of which have a lot of mitochondria - students are asked to make the link between the number of mitochondria, the function of the specialised cell, and how much energy that would require. Further analysis of the topic links it with the digestion of carbohydrates to get glucose ,and how oxygen is transported from the lungs to the tissues for aerobic respiration.
