Phase 5: Spread of disease between humans is occurring in more than one country of one WHO region. Phase 6: Community-level outbreaks are in at least one additional country in a different WHO region from phase 5. A global pandemic is under way.
Figure %: The Electron Transport Chain. The events of the electron transport chain involve NADH and FADH, which act as electron transporters as they flow through the inner membrane space. In complex I, electrons are passed from NADH to the electron transport chain, where they flow through the remaining complexes. NADH is oxidized to NAD in this process.
The electron transport chain is the path in which the electrons travel during cellular respiration. The electron transport system is the set of proteins and other cellular câ¦omponents that are involved in the electron transport chain. For example, the both aerobic and anaerobic organisms, there are different electron transport systems and this influences the path electrons take.
