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.
Challenge opportunities throughout + worksheet
Many answers animate onto screen to allow opportunity of peer/self assess
