Question

Identify the correct statements for ATP synthase.
(i) This enzyme consists of two parts: hydrophobic membrane bound portion called F₀ & a portion that sticks out into stroma called F₁.
(ii) F₀ appears to form a channel across the membrane through which proton can pass.
(iii) The conformational change in the F₁ portion of the complex synthesizes ATP.
(iv) The proton motive force that drives the synthesis of ATP is associated with this enzyme.

• A. (i), (ii) and (iii)
• B. (i), (ii) and (iv)
• C. (i) and (iv) only
• D. All of these

Answer 1

The correct option is D All of these

All the statements regarding ATP synthase are correct. ATP synthase is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms.
