By What does the term oxidative phosphorylation refer to?
Oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH 2 to O 2 by a series of electron carriers.
What is the main function of oxidative phosphorylation?
What is oxidative phosphorylation? Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria (called the electron transport chain and ATP synthase) to create ATP.
Why is it called oxidative phosphorylation?
In the mitochondrion, what the proton gradient does is facilitate the production of ATP from ADP and Pi. This process is known as oxidative phosphorylation, because the phosphorylation of ADP to ATP is dependent on the oxidative reactions occurring in the mitochondria.
What is oxidative phosphorylation quizlet?
Oxidative Phosphorylation. The process by which ATP is formed as a result of the transfer of electrons from NADH and FADH₂ to O₂ by a series of electron carriers. Proton-motive force. transfer of electrons leads to the pumping of protons. Takes place across the inner mitochondrial membrane that’s used to synthesize ATP.
What is the meaning of phosphorylation?
Listen to pronunciation. (fos-FOR-ih-LAY-shun) A process in which a phosphate group is added to a molecule, such as a sugar or a protein.
Where does the oxidative phosphorylation occur?
Oxidative phosphorylation takes place in the inner mitochondrial membrane, in contrast with most of the reactions of the citric acid cycle and fatty acid oxidation, which take place in the matrix.
What is meant by uncoupling of oxidative phosphorylation?
Abstract. Uncouplers of oxidative phosphorylation in mitochondria inhibit the coupling between the electron transport and phosphorylation reactions and thus inhibit ATP synthesis without affecting the respiratory chain and ATP synthase (H(+)-ATPase).
What is oxidative phosphorylation Class 11?
Complete answer: Metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing the chemical energy stored within in order to produce adenosine triphosphate (ATP) is called oxidative phosphorylation. This process takes place inside the mitochondria of the cell.
What occurs during oxidative phosphorylation quizlet?
A process occurring in the mitochondria that results in the formation of ATP from the flow of electrons across the inner membrane to bind with oxygen. The potential energy stored in the form of an electrochemical gradient, generated by the pumping of hydrogen ions across biological membranes during chemiosmosis.
Where is oxidative phosphorylation occur?
inner mitochondrial membrane
Oxidative phosphorylation takes place in the inner mitochondrial membrane, in contrast with most of the reactions of the citric acid cycle and fatty acid oxidation, which take place in the matrix.
What is phosphorylation in biology class 10?
Phosphorylation is the process by which a phosphoryl group attaches to the molecules. Dephosphorylation also occurs in the cells which is the removal of phosphate groups from the molecules. Enzymes activated when the phosphorylation occurs in the cell. In eukaryotes, Phosphorylation occurs in sugars and lipids.
What organelle is oxidative phosphorylation?
mitochondria
Oxidative phosphorylation occurs in the mitochondria. The mitochondrion has two membranes: an inner membrane and an outer membrane.
