The illustration to the left represents a mixture of nitrogen (blue) and oxygen (red) molecules. if the molecules in the above illustration react to form n2o4 according to the equation n2 + 2o2 n2o4the limiting reagent number of n2o4 molecules formed number in excess

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.
