Refer to the Table Below, Showing Data Collected from Experiments

Multiple Choice

Refer to the table below, showing data collected from experiments using purified soybean mitochondria incubated in buffer containing compound X, compound Y, or no additions.Three different assays were performed on each group of mitochondria to determine the rate of oxygen uptake, ATP synthesis, and formation of a hydrogen ion gradient.The results are expressed as a percentage relative to the control group. Which conclusion is consistent with these results?

A) Compound X and compound Y inhibit different proteins in the respiratory chain.
B) Compound X and compound Y both uncouple electron transport from ATP synthesis.
C) Compound X uncouples electron transport from ATP synthesis, and compound Y inhibits a protein in the respiratory chain.
D) Compound X inhibits a protein in the respiratory chain, and compound Y uncouples electron transport from ATP synthesis.
E) Compound X prevents oxygen from functioning as the final electron acceptor, and compound Y inhibits a protein in the respiratory chain.
