In Prokaryotes,the Respiratory Electron Transport Chain is Located

Question

In prokaryotes,the respiratory electron transport chain is located
A)in the mitochondrial inner membrane.
B)in the mitochondrial outer membrane.
C)in the plasma membrane.
D)in the cytoplasm.
E)in the bacterial outer membrane.

Accepted Answer

In prokaryotes, which lack mitochondria, the respiratory electron transport chain is located in the plasma membrane. This is where the electron transport chain proteins are embedded and proton pumping occurs to generate a proton motive force for ATP synthesis via ATP synthase.
