Example Question #1 : Prokaryotic Cell Functions
Where in prokaryotes do the reactions of the electron transport chain take place?
Possible Answers:
Cytosol
Inner mitochondrial membrane
Inner cytoplasmic membrane
Mitochondrial matrix
Periplasmic space
Correct answer:
Inner cytoplasmic membrane
Explanation:
The correct answer is the inner cytoplasmic membrane. Prokaryotes do not have mitochondria or any other membrane-enclosed organelles, but the electron transport chain must be performed in a membrane in order to create a concentration gradient of protons; therefore, prokaryotes perform the redox reactions of the electron transport chain in the inner cytoplasmic membrane in between the cytosol and the periplasmic space.
