Answer 1

Answer:

When electrons move through a series of electron acceptor molecules in cellular respiration, oxygen is eventually reduced by the electrons in the formation of water

Explanation:

The electron transport chain is located in the internal mitochondrial membrane. There are three proteinic complexes in the membrane, I, II, and III, that contain the electrons transporters and the enzymes necessary to catalyze the electrons transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I to complex II. The complex II contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex III. Finally, electrons go back to the matrix, where they combine to H₊ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through the three proteinic complexes from the matrix to the intermembrane space.
