AP Biology, Unit 3, Lesson 3

In Unit 3 Lesson 3, I noticed that reaction coupling, ΔG calculations, and the distinction between exergonic and endergonic reactions weren't covered before the video ‘Reaction Coupling to Create Glucose-6-Phosphate’. I know you often connect content across separate lessons, but please add a video with a deeper introduction to these topics before the ‘Reaction Coupling to Create Glucose-6-Phosphate’ video. I’ve found that the layout of your introductory videos and the concluding review articles works really well for me, and I think including this background would make the lesson even clearer. Thank you for your courses.
