試題詳解

15. If electron transfer in tightly coupled mitochondria is blocked (with antimycin( A ) between cytochrome b and cytochrome cl, then:
(A) all ATP synthesis will stop.
(B)ATP synthesis will continue, but the P/O ratio will drop to one.
(C) electron transfer from NADH will cease, but O2 uptake will continue.
(D) electron transfer from succinate to O2 will continue unabated.

(E) energy diverted from the cytochromes will be used to make ATP, and the P/O ratio will rise.
