what is the final electron acceptor in the mitochondrial etc and what does it become after
accepting electrons?
glucose; co2
water; oxygen gas
oxygen; water
atp; adp
nadh; nad+

Explanation:

In the mitochondrial electron - transport chain (ETC), oxygen (\(O_2\)) acts as the final electron acceptor. The electrons are passed through a series of protein complexes in the ETC. When oxygen accepts electrons (\(e^-\)) and protons (\(H^+\)), it is reduced. The chemical reaction is \(O_2 + 4e^-+4H^+\to2H_2O\). So, oxygen (\(O_2\)) is the final electron acceptor and it becomes water (\(H_2O\)) after accepting electrons.

Answer:

Oxygen; water
