Explanation:
Detailed explanation-1: -The final electron acceptor is oxygen (O2). Oxygen has a high electronegativity; thus, oxygen’s high affinity for electrons makes it an ideal acceptor for low-energy electrons. With the electrons, hydrogen is added to oxygen forming water as the final product.
Detailed explanation-2: -The final electron acceptor is oxygen (O2), it has a high electronegativity and accepts low-energy electrons. Hydrogen is combined with oxygen, forming water as the final product.
Detailed explanation-3: -Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water.
