Question

Why does the electron transport chain stop without oxygen?

Answer 1

Electron transport chain

1. An electron transport chain is a collection of protein complexes and other molecules that associate protons across a membrane with the transfer of electrons from electron donors to electron acceptors via redox processes.
2. The electron transport chain's final electron acceptor, oxygen, enables oxidative phosphorylation.
3. Without oxygen, the electrons will become backed up and the electron transport cycle will eventually come to an end.
4. The electron transport chain (ETC), a crucial aspect of cellular respiration, is a system where oxygen plays a crucial role in energy production.
5. Adenosine triphosphate, the primary cellular energy source, is created by the electron transport chain.
