Which statement is CORRECT concerning the mitochondrial ATP synthase? A) It can synthesize ATP after it is extracted from broken mitochondria. B) It catalyzes the formation of ATP even though the reaction has a large positive $\Delta$G'°. C) It consists of F_o and F₁ subunits, which are transmembrane (integral) polypeptides. D) It is actually an ATPase and only catalyzes the hydrolysis of ATP. E) When it catalyzes the ATP synthesis reaction, the $\Delta$G'° is actually close to zero.

The correct statement concerning mitochondrial ATP synthase is that when it catalyzes the ATP synthesis reaction, the F1F1F1S1F1F1F10G'° is actually close to zero. This means that the reaction is not energetically favorable, but the enzyme is able to overcome this barrier and synthesize ATP. Option A is incorrect because ATP synthase is an integral membrane protein and cannot synthesize ATP once extracted from the mitochondria. Option B is incorrect because the reaction has a large positive Gibbs free energy change, which is unfavorable for the synthesis of ATP. Option C is incorrect because ATP synthase has several subunits, including the F1 and Fo subunits, but not all of them are transmembrane polypeptides. Option D is incorrect because ATP synthase can function as both an ATPase and an ATP synthase.
