The mitochondrial electron transfer chain
A cartoon representation of the mitochondrial electron transfer chain. The main complexes are shown, with their substrates in black. Inhibitors are shown in bold itallic, approximately at their sites of action; electron donors (red) and acceptors (blue) allowing dissection of partial reactions of the chain are also shown.
