Which statement about uncouplers is NOT true? A. They allow ATP synthesis with no electron transport. B. They allow electron transport without ATP synthesis. C. Their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side. 2,4-DNP is an example of an uncoupler.

Answer: the statement that is wrong about uncouplers is option A (they allow ATP synthesis with no electron transport).

Explanation:

An uncoupler is a molecule that disrupts oxidative phosphorylation by dissociating the reactions of ATP synthesis from the electron transport chain. They allow electron transport without ATP synthesis. Their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side.

2,4-DNP is an example of an uncoupler.
