How is ATP made by an acetogen during CO2 fixation?
A. Electrons from metal cofactors energize the electron transport chain and drive the proton motive force to activate ATP synthase.
B. Substrate-level phosphorylation of ADP occurs when coenzyme A is removed from acetyl-CoA.
C. It is made by substrate-level phosphorylation and a Na+-translocating ATPase.
D. The energized CO-CH3 complex during thioesterification drives a Na+-translocating ATPase.
