A vital process of intracellular respiration occurring within the mitochondria of the cell, responsible for most ATP production.
electron transport occurring in a complex, incomplete understood series of reactions after products of glycolysis have passed through the Krebs cycle; yields 34 additional ATP molecules.
The production of ATP, using the potential energy of a proton gradient formed through an electron transport chain.
Part of the electron transport chain. 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 utilisation of energy released by the oxidative reactions of respiration to form high energy ATP bonds.
The synthesis of the energy storage compound adenosine triphosphate (ATP) from adenosine diphosphate (ADP) using a chemical substrate and molecular oxygen.
an enzymatic process in cell metabolism that synthesizes ATP from ADP
ox-i-DAY-tiv fos-for-e-LAY-shun Phosphorylation of ADP to ATP coupled to protons moving down their concentration gradient across the inner mitochondrial membrane. 129
Synthesis of ATP through various reactions whereby energy for the cell is obtained
The formation of high-energy phosphate bonds via phosphorylation of ADP to ATP, accompanied by the transport of electrons to oxygen from the substrate.
Oxidative phosphorylation is the terminal process of cellular respiration in eukaryotes. During oxidative phosphorylation electrons are transferred from NADH or FADH2 — created in glycolysis, fatty acid metabolism and the Krebs cycle — to molecular oxygen, via a series of protein complexes located in the inner mitochondrial membrane. Protons are pumped from the mitochondrial matrix into the intermembrane space as a result of this flow of electrons.
