Question

Antimycin A that inhibits electron transfer between ubiquinone and complex III of the electron transport chain. A. Which component(s) of the electron transport chain become reduced and which become oxidized following treatment with antimycin A? B. Explain the effect of antimycin A on the synthesis of ATP (ie; if it increases or decreases or stays the same, explain why). C. Explain the effect of antimycin A on oxygen consumption (ie; if it increases or decreases or stays the same, explain why). D. Following the addition of antimycin A, you add an uncoupler (FCCP) to dissipate the proton gradient. Does the rate of O2 consumption increase, decrease or remain the same? Why?
