ATP Synthase - an overview ScienceDirect Topic

ATP synthase is an enzyme that directly generates adenosine triphosphate (ATP) during the process of cellular respiration. ATP is the main energy molecule used in cells. ATP synthase forms ATP from adenosine diphosphate (ADP) and an inorganic phosphate (Pi) through oxidative phosphorylation, which is a process in which enzymes oxidize nutrients to form ATP P/O is the number of ATP molecules synthesized by oxidative phosphorylation for each pair of electrons (hence, not P/O 2) passing from a particular substrate, typically NADH or succinate, via a respiratory chain, to O 2. Knowledge of the P/O ratio is fundamental for understanding the ATP yield from cell fuels and is a core metabolic parameter

The ATP synthase uses the energy to transform adenosine diphosphate (ADP) into adenosine triphosphate, in a phosphorylation reaction. The reaction is driven by the proton flow, which forces the rotation of a part of the enzyme. The ATP synthase is a rotary mechanical motor ATP Synthase animationMicrobiology: An Evolving Science 3rd editionCopyright: WW Norton 2016Used for Educational purposes only. I do not own this video.ch14a.. Enzyme Nomenclature, the enzyme is called ATP phosphohydrolase (H+-transporting). However, the name ATP synthase reflects the primary function of the enzyme more clearly and nowadays is most wide-spread. The other name that was commonly used in the past is H+-ATPase In most systems, the ATP synthase sits in the membrane (the coupling membrane), and catalyses the synthesis of ATP from ADP and phosphate driven by a flux of protons across the membrane down the proton gradient generated by electron transfer ATP synthase is a ubiquitous membrane enzyme that plays a key role in biological energy metabolism. This enzyme interconverts two major energy currencies of a living cell: adenosine triphosphate (ATP) and transmembrane electrochemical proton potential difference. ATP synthase is found in bacteria, plants, and animals

ATP synthase manufactures ATP from two smaller chemicals, ADP and phosphate Here, we identify the mitochondrial α-F 1 -ATP synthase (ATP5A) as a target for J147.

At this stage, the ATP synthase is present at reduced, although significant, levels. To test whether the ATP synthase at this stage is important for maintaining the mitochondrial membrane potential, we used RNA interference (RNAi) to knock down.
