True, they use a very similar ATP Synthase to eukaryotic cells.

|
False. Bacteria use a different synthase to make ATP

Detailed explanation-1: -ATP synthases (FoF1) are found ubiquitously in energy-transducing membranes of bacteria, mitochondria, and chloroplasts. These enzymes couple proton transport and ATP synthesis or hydrolysis through subunit rotation, which has been studied mainly by observing single molecules.
Detailed explanation-2: -Structure of ATP Synthase ATP Synthase has two parts. The part embedded within the membrane of the mitochondria (in eukaryotes), thylakoid membrane of the chloroplast (only in plants), or plasma membrane (in prokaryotes) is called FO.
Detailed explanation-3: -The overall structure and the catalytic mechanism of the chloroplast ATP synthase are almost the same as those of the bacterial enzyme. However, in chloroplasts, the proton motive force is generated not by respiratory electron transport chain but by primary photosynthetic proteins.
Detailed explanation-4: -The ATP synthase is a mitochondrial enzyme localized in the inner membrane, where it catalyzes the synthesis of ATP from ADP and phosphate, driven by a flux of protons across a gradient generated by electron transfer from the proton chemically positive to the negative side.
