Additionally, there are other important molecules in the ETC:

  • Ubiquinone (Coenzyme Q): A non-protein lipid-soluble molecule that transfers electrons between Complex I or II and Complex III.
  • Cytochrome c: A small protein that shuttles electrons from Complex III to Complex IV.

The Electron Transport Chain is an essential part of cellular respiration, and its efficient functioning is critical for the generation of ATP, the energy currency of the cell.
