  2. F-ATPase - Wikipedia

    en.wikipedia.org/wiki/F-ATPase

    F-ATPase, also known as F-Type ATPase, is an ATPase/synthase found in bacterial plasma membranes, in mitochondrial inner membranes (in oxidative phosphorylation, where it is known as Complex V), and in chloroplast thylakoid membranes.

    The formation of ATP is energetically unfavorable and would not normally proceed. In order to drive this reaction forward, ATP synthase couples ATP synthesis to an electrochemical gradient that drives rotational motor mechanism allowing for ATP production. Because of its rotating subunit, ATP synthase is a molecular machine.

  4. ATP synthase - Wikipedia

    en.wikipedia.org/wiki/ATP_synthase

    ATP synthase is an enzyme that catalyzes the formation of the energy storage molecule adenosine triphosphate (ATP) using adenosine diphosphate (ADP) and inorganic phosphate (P i). ATP synthase is a molecular machine. The overall reaction catalyzed by ATP synthase is: ADP + P i + 2H + out ⇌ ATP + H 2 O + 2H + in

  5. Adenosine diphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_diphosphate

    The ATP synthase complex exists within the mitochondrial membrane (F O portion) and protrudes into the matrix (F 1 portion). The energy derived as a result of the chemical gradient is then used to synthesize ATP by coupling the reaction of inorganic phosphate to ADP in the active site of the ATP synthase enzyme; the equation for this can be ...

  6. ATP synthase alpha/beta subunits - Wikipedia

    en.wikipedia.org/wiki/ATP_synthase_alpha/beta...

    ATPases (or ATP synthases) are membrane-bound enzyme complexes/ion transporters that combine ATP synthesis and/or hydrolysis with the transport of protons across a membrane. ATPases can harness the energy from a proton gradient, using the flux of ions across the membrane via the ATPase proton channel to drive the synthesis of ATP. Some ATPases ...

  7. ATPase - Wikipedia

    en.wikipedia.org/wiki/ATPase

    F-ATP synthases are identical in appearance and function except for the mitochondrial F 0 F 1-ATP synthase, which contains 7-9 additional subunits. [12] The electrochemical potential is what causes the c-ring to rotate in a clockwise direction for ATP synthesis. This causes the central stalk and the catalytic domain to change shape.

  8. Proton ATPase - Wikipedia

    en.wikipedia.org/wiki/Proton_ATPase

    F-type proton ATPase [12] [13] (or F-ATPase) typically operates as an ATP synthase that dissipates a proton gradient rather than generating one; i.e. protons flow in the reverse direction compared to V-type ATPases. In eubacteria, F-type ATPases are found in plasma membranes.

  9. Oxidative phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Oxidative_phosphorylation

    Mechanism of ATP synthase. ATP is shown in red, ADP and phosphate in pink and the rotating γ subunit in black. This ATP synthesis reaction is called the binding change mechanism and involves the active site of a β subunit cycling between three states. [77] In the "open" state, ADP and phosphate enter the active site (shown in brown in the ...
