Indirect atp formation

  1. May 5, 2015 #1
    I came across a term "indirect atp formation"I am not sure what it is ?
    What is the difference between direct and indirect atp synthesis?I think substrate level phosphorylation (where a molecule directly donates a phosphate to ADP) is direct atp synthesis.Indirect atp synthesis is oxidative phosphorylation (in the electron transport chain; using the H+ gradient to attach inorganic phosphate to ADP).

    The phosphate need not come from the molecule, the energy liberated during the conversion might just help in adding that Pi to ADP/GDP, eg:succinyl CoA to succinic acid in kreb's cycle.
    Yes, by PMF(proton motive force) and oxysomes(FoF1 particle)
