Where are the corresponding reactions likely to occur in prokaryotic respiration?

Correct answer is Inner plasma membrane.
Unlike the eukaryotic cell that synthesizes ATP primarily on the inner membrane of the mitochondria; prokaryotic cells synthesize ATP primarily on the inner plasma membrane.

Remember, prokaryotic cells lack mitochondria, which is a membrane bound organelle, so they cannot synthesize ATP on the inner mitochondria membrane.

Prokaryotic cells do not have a cell nucleus or any membrane bound organelles.

Prokaryotes have their ATP synthesis machinery present in the plasma membrane not cytoplasm. Hope this helps.
