試題詳解

48. 2,4-Dinitrophenol and oligomycin inhibit mitochondrial oxidative phosphorylation. 2,4-Dinitrophenol is an uncoupling agent; oligomycin blocks the ATP synthesis reaction itself. Therefore, 2,4-dinitrophenol will:
(A) allow electron transfer in the presence of oligomycin.
(B) allow oxidative phosphorylation in the presence of oligomycin.
(C) block electron transfer in the presence of oligomycin.
(D) diminish O₂ consumption in the presence of oligomycin.
(E) None of the above.
