Oxidative phosphorylation (UK / ɒ k ˈ s ɪ d. ə. t ɪ v /, US / ˈ ɑː k. s ɪ ˌ d eɪ. t ɪ v / or electron transport-linked phosphorylation) is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing energy which is used to produce adenosine triphosphate (ATP). In . And what I want to talk about in this video is the process by which we actually are able to produce ATP from the oxidation of these coenzymes, and that process is what we call Oxidative Phosphorylation. Oxidative, Oxidative Phosphorylation. Now the main player, when we're talking about cellular respiration and Oxidative Phosphorylation, is NADH.

Oxidative phosphorylation regulated by energy charge •the rate of O₂ consumption increases when ADP is added •OxPhos coordinates w/ the TCA cycle. An active ETC increase the activity of the TCA cycle due to lowered level of NADH. Heat generation (nonshivering thermogenesis). Overview of oxidative phosphorylation. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.

An overview of the mechanism of electron transport reveals a requirement for many essential coenzymes. We will discuss the normal tight coupling and consequences of uncoupling: 1) Identify enzymes and cofactors required for oxidative phosphorylation. 2) Describe the mechanism of ATP synthesis and the overall yields from oxidative phosphorylation. 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. This process, which takes place in mitochondria, is the major source of ATP in aerobic organisms (Figure ).

Oxidative phosphorylation is a highly efficient method of producing large amounts of ATP, the basic unit of energy for metabolic processes. During this process electrons are exchanged between molecules, which creates a chemical gradient that allows for the production of ATP.
