The process by which the proton gradient drives adenosine triphosphate (ATP) synthesis in chemiosmosis. 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.

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.
