What is the ETC?

→ series of electron transporters embedded in the inner mitochondrial membrane that shuttle electrons from NADH and FADH2 to molecular oxygen.

What is oxidative phosphorylation?

→ process in which ATP is formed as a result of the electrons from NADH/FADH2 being transferred to oxygen by a series of electron carriers

Complex 1

NADH-Q Oxoreductase/NADH dehydrogenase

  • 880 Kd

  • At least 34 polypeptides

  • Contains flavin mononucleotide (FMN) and Iron-Sulphur clusters (Fe-S)

  • Pumps H+ into intermembrane space
