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?
A) in the cytoplasm
B) on the inner mitochondrial membrane
C) on the endoplasmic reticulum
D) on the plasma membrane
E) on the inner nuclear envelope

Question

Quizplus · Accepted Answer

Since mitochondria evolved from prokaryotic cells, it is likely that the location of ATP synthesis in prokaryotic cells would be similar to that of the inner membrane of mitochondria. In prokaryotic cells, this would correspond to the plasma membrane.
