Explanation:
The following are the statements that accurately demonstrate the electron transport chain:
1. The electron transfer in the electron transport chain is combined with the proton transfer from the matrix to the intermembrane space.
2. The prosthetic groups, like Fe-S centers, directly take part in the transfer of electrons.
3. The electron carriers in the electron transport chain comprise cytochrome C and ubiquinone (coenzyme Q).
4. The electron carriers are arranged into four complexes of prosthetic groups and proteins.
5. The reactions of the electron transport chain occur in the inner membrane of mitochondria.
