Answer:
C & D
Step-by-step explanation:
The correct statements explaining the differences between prokaryotic and eukaryotic cells are:
C. In eukaryotes, the electron transport chain is composed of a series of electron transport proteins located in the inner mitochondrial membrane.
D. In prokaryotes, the electron transport chain is in the cell membrane.
Statement A is not correct, as in prokaryotes, the electron transport chain is typically located in the cell membrane, not the nucleus.
Statement B is not accurate because it is incomplete and doesn't provide a full explanation of the differences.
