Which of the following statements correctly describe the thermodynamics and kinetics of oxidative phosphorylation when demand for ATP is high? Mark all that apply
a.Because of the large amount of energy stored in the proton gradient, the ATP synthase reaction is always irreversible and must be regulated by kinetics.
b.The ATP synthase and electron transport chain reactions are always reversible and have no driving force, regardless of the amount of ATP used by the cell.
c.A decrease of [ATP] and increase of [ADP] due to ATP consumption changes the thermodynamics of the ATP synthase reaction, making it slightly irreversible and providing a driving force for ATP synthesis.
d.A decrease of [ATP] and increase of [ADP] due to ATP consumption leads to allosteric activation of ATP synthase and the electron transport chain complexes.
