The chemical reactions involved in respiration are virtually identical between prokaryotic and eukaryotic cells. in eukaryotic cells, atp is synthesized primarily on the inner membrane of the mitochondria. in light of the endosymbiont theory for the evolutionary origin of mitochondria, where is most atp synthesis likely to occur in prokaryotic cells?

In the cytoplasm and plasma membrane.

Explanation:

On bacteria, the cytoplasm harbors the majority of the TCA cycle enzymes, and the electron transport proteins are located on the cell membrane (also called plasma membrane). So, the mitochondrial matrix and inner membrane has similar functions to the bacteria plasmatic membrane and cytoplasm.

hey, what do you need . just post the question and i may be able to you : )
