Mouse Mitochondria Were Isolated and Incubated with Two Different Compounds

Multiple Choice

Mouse mitochondria were isolated and incubated with two different compounds to see whether they affected FADH₂ oxidation, NADH oxidation, or ATP formation.A control sample was run in the absence of either compound.The results are summarized in the table as "yes" if a process was observed and "no" if a process was not observed. Which statement is consistent with these data?

A) Compound Z inhibits a component of the electron transport chain, while compound A inhibits ATP synthase.
B) Compound A inhibits a component of the electron transport chain, while compound Z inhibits ATP synthase.
C) Compound Z inhibits the first component of the electron transport chain, while compound A inhibits a later component of the chain.
D) Compound A inhibits the first component of the electron transport chain, while compound Z inhibits a later component of the chain.
E) Compound A and compound Z both directly interfere with the final transfer of electrons to oxygen.
