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?
1. in the cytoplasm
2. on the inner mitochondrial membrane
3. on the endoplasmic reticulum
4. on the plasma membrane
1. in the cytoplasm
