Ubiquinone, a metabolite critical to generating energy in cells, has long been thought to be the only mitochondrial electron transport chain carrier in mammals. Although other electron transporters ...

The high resolution structure of photsystem I reveals ... Figure 1: A schematic diagram of the electron-proton transport chain of oxygenic photosynthesis. Both PSI and PSII are multisubunit ...

At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this ...
