Figure 2
Figure 2 The electron transport chain is located on the inner mitochondrial membrane. Electrons (e-) enter through complex I or II and are transferred to complex III by coenzyme Q (Q). Electrons then move between complex III and IV by cytochrome c (c). Electrons can leak from the chain and react with oxygen to create superoxide (O2-). The movement of electrons is coupled to the pumping of protons (H+) from the mitochondrial matrix into the intermembrane space (IMS). This gradient is then used by ATP synthase, or complex V, to generate ATP.
