7:13 minutes (4:27 - 11:40)

Chlorophyll captures sunlight, creates a proton gradient, which makes ATP as a form of energy storage. In addition to ATP energy, organisms also needed a source of reducing power (NADPH or H2O).

Instructors: Prof. Penny Chisholm, Prof. Graham Walker, Dr. Julia Khodor, Dr. Michelle Mischke
Prior Knowledge: Proton gradient; electron orbitals and excitations
