The chemical reactions involved in respiration in prokaryotic and eukaryotic cells are virtually identical. 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?

Question

Quizplus · Accepted Answer

Prokaryotic cells lack membrane-bound organelles like mitochondria, but they do have plasma membranes which perform similar functions. In prokaryotic cells, ATP synthesis occurs mainly on the plasma membrane as electron transport chains and oxidative phosphorylation take place here.
