The role of electron transport chain, proton gradient, and ATP synthase complex in chemiosmosis ATP synthesis. Concept introduction: The process in which ions are moved by diffusion across a semi-permeable membrane to synthesize ATP is known as chemiosmosis. This process takes place inside the mitochondria during the aerobic cellular respiration . During the course of chemiosmosis ions move down an electrochemical gradient (gradient of electrochemical potential) by ATP synthase. The ATP synthase harnesses the proton-motive force to phosphorylate adenosine diphosphate (ADP) and form ATP.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

What essential role does each of the following play in chemiosmotic ATP synthesis: (1) electron transport chain, (2) proton gradient, and (3) ATP synthase complex?

Much of our understanding of ATP synthase is derived from research on aerobic bacteria. What makes these organisms useful for this research? Where do the reactions of glycolysis, the citric acid cycle, and the electron-transport chain occur in these organisms?

What steps in glycolysis generate substrate-level phosphorylation, and how many ATP molecules are generated in this way in this pathway? How does the generation of ATP by substrate-level phosphorylation differ from ATP generation by oxidative phosphorylation?
