Which of the following ranks the redox-active species of the electron transport chain in order of decreasing electron affinity?

a. o2 > fad > coq > nad+
b. nad+ > fad > coq > o2
c. o2 > coq > nad+ > fad
d. o2 > coq > fad > nad+

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.
