The final acceptor of electrons in the electron transport chain is "C" , that is oxygen.
The electron transport chain is composed of a series of electron carriers that operate together to transfer electrons from donors, like NADH and FADH2, to acceptors such as O2.
The electrons flow from carriers with more negative reduction potentials to those with more positive potentials and eventually combine with O2 and H+ to form water.
The difference in reduction potentials between oxygen and NADH is large, about 1.14 volts and makes possible the release of a great deal of energy.
Sorry I can’t help on this if there is no answer choices.
Answer:
Selectively permeable or semipermeable means specific substances are allowed to pass through the plasma membrane.
Explanation:
The plasma membrane is selectively or semipermeable in nature because the plasma membrane allow only specific molecules such as nonpolar substances or hydrophobic substances such as steroidshormone to pass through it and prevent the passage of polar solute molecules such as water,glucose.
To transport these polar solutes across the membrane an additional protein is needed in case of transport of water channel protein is needed whereas in case of glucose transport carrier protein is required.
