Question

the final electron acceptor for the electrons after they have moved completely through the electron transport chain is
the amount of atp produced as electrons move through the electron transport chain is
the compound that is formed as a final product of the electron transport chain (oxygen is reduced to form this) is

Explanation:

In the electron - transport chain, oxygen is the final electron acceptor. As electrons move through the chain, a proton gradient is established which is used to generate ATP. The amount of ATP produced can vary but is approximately 34 - 36. When oxygen is reduced by the electrons and protons, water ($H_2O$) is formed as the final product.

Answer:

The final electron acceptor for the electrons after they have moved completely through the electron - transport chain is O2.
The amount of ATP produced as electrons move through the electron - transport chain is 34 - 36.
The compound that is formed as a final product of the electron - transport chain (oxygen is reduced to form this) is H2O.
