An engaging and detailed lesson presentation (37 slides) that uses a step-by-step guide to go through the details of the final stage of aerobic respiration, oxidative phosphorylation. The lesson begins by challenging the students to work out what the starting substances of this stage will be, considering that the Kreb's cycle does not have an obvious end-product as was seen with the Link reaction and glycolysis. Students will learn that the reduced coenzymes, NAD and FAD, release their hydrogen atoms and this is the starting point. From then on, a guide is used to look at each fine detail of this stage. Key terms such as chemiosmosis are introduced and discussed and the yield of ATP explained with reference to the ATP synthase enzyme. There are a number of quick competitions in the lesson to maintain motivation and there are also regular progress checks so that students can assess their understanding.
This lesson is designed for A-level students
