Which is the final electron acceptor in the electron transport system of cellular respiration? nadh fadh2 oxygen carbon dioxide

The right answer is Oxygen.

The respiratory chain transports both protons and electrons. The latter circulate from donors to electron acceptors, while the protons circulate through the membrane. These processes use transfer molecules some of which are soluble while others are linked to proteins.

O2 molecular oxygen is a strong oxidizer, making it an excellent final acceptor of electrons.

answer; i believe that the correct answer is (lung);

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
