I have now completed a fully animated PowerPoint for topic 5 of Edexcel A Level Biology B. This covers the biochemical processes of cellular respiration and photosynthesis. You can view a sample of the PowerPoint here:
It is probably my most advanced presentation to date, with complex animations for the electron transport chain and photophosphorylation.
It is designed for the Edexcel syllabus but would be a suitable resource for any A Level or post 16 biology course.
Even better, I am now working hard to produce teaching videos for all my topics. These feature stripped back versions of the PowerPoint with my explanations. The playlists for respiration and Photosynthesis can be found here.
