Answer:
See the answer below
Step-by-step explanation:
Eukaryotic organisms or eukaryotes have nuclei and membrane-bound organelles such as mitochondrion and chloroplasts, unlike prokaryotic cells/prokaryotes.
In eukaryotic organisms, the process of electron transport - a part of the respiratory process - happens in the inner membrane of the mitochondrion through a series of electron carriers.
Because prokaryotes lack mitochondrion, the electron transport chain takes place in the cell membrane as an improvisation.
Hence, the difference in the location of the electron transport chains of eukaryotes and prokaryotes is due to the mitochondrion.
