Answer #1

The correct answer is mitochondrial inner membrane. In a eukaryotic cell, the electron transport chains take part in oxidative phosphorylation. They help in the ATP formation by use of ATP synthase and the electrons. A proton gradient is created across the membrane. In an eukaryotic plant cell, it is located in thylakoid membrane of the chloroplast and helps in photosynthesis. While, in prokaryotes it occurs in the plasma membrane.
