본문내용
Organism uses the energy of "ATP (adenosine triphoshphate)" for many celluar processes like metabolism, motility, and active transport of molecules across cell membranes through which molecules move AGAINST concentration gradient. To synthesize ATP energy for the cell to consume, there should be "ATP Synthase" (von Ballmoos, Wiedenmann, Dimroth, 2009). ATP Synthase are found in all organisms that undergo aerobic respiration and are located where cellular respiration takes place: the cell membrane in prokaryotes, the mitochondrial inner membrane in eukaryotes, and the chloroplast thylakoid membrane. In every case, ATP synthases take advantage of the electrochemical energy derived from a transmembrane proton or sodium (Na+) gradient to synthesize ATP by combining ADP and inorganic phosphate (Pi) (Ackerman, Tzagoloff, 2005). In case of eukaryotes, the proton pumps of the mitochondrial electron transport chain create a proton gradient, where the pH is lower (there is a greater H+ concentration) in the intermembrane space (P side) than in the mitochondrial matrix (N side) (Nelson, Cox, 2008).
