During the final stage of cellular respiration, 36 molecules of ATP are produced as proteins embedded in the membrane move hydrogen ions across the cell membrane and back again. As hydrogen ions diffuse back into the matrix a phosphate group is added to ADP making it ATP. What is this final stage of cellular respiration called where the most ATP molecules are made? best award to best answer
Krebs Cycle
Electron Transport Chain
Glycolysis
