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.

Students have asked these similar questions

the reaction catalyzed by glyceradehyde 3-phosphate dehydrigenase is based on NAD+ and a active site cysteine. Also another phosphate group is added. what is the reason for that? a) because one ATP is consumed b) an inorganic phosphate is activated for ATP synthesis C) NADH can be recycld and than converted back to NAD+ for glycolysis d) because one ATP is generated

A proton gradient is created during the electron transport chain using the energy released from the oxidation of NADH and FADH2. The protons then cross the membrane through ATP synthase down their electrochemical gradient, and ATP is produced. This is an example of A) energy coupling B) cotransport C) allosteric regulation.
