This complex, labeled I, is composed of flavin mononucleotide (FMN) and an iron-sulfur (Fe-S)-containing protein. If oxygen isn’t present to accept electrons, the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis. Electron transport is a series of redox reactions that resemble a relay race. A prosthetic groupis a non-protein molecule required for the activity of a protein. Each electron is then passed from the cytchrome b-c1 complex to cytochrome c. Cytochrome c accepts each electron one at a time.
