The role of O2 in electron transport
In mitochondrial electron transport, what is the direct role of O2?
From the given data,
The role of \(\mathrm{O}_{2}\) in electron transport in mitochondrial electron transport is to function as the final electron acceptor in the electron transport chain. After accepting the final electron oxygen becomes completely reduced into a water molecule. The adjoined picture shows ETC:
Thus, the correct option is to function as the final electron acceptor in the electron transport chain.
