Cyanide Differs from Dinitrophenol in That

Cyanide differs from dinitrophenol in that

A) cyanide inhibits the production of ATP by inhibiting ATP synthase,while dinitrophenol causes mitochondrial membranes to become less permeable to H+ ions.
B) cyanide makes the membrane of mitochondria leaky to H+ ions and prevents a concentration gradient from building up,while dinitrophenol blocks the passage of electrons through electron carriers.
C) cyanide is highly toxic to human cells,while dinitrophenol is nontoxic.
D) cyanide is an electron transport blocker,while dinitrophenol makes the membrane of the mitochondrion leaky to H+ ions.
