The ratio of h2 gas to o2 gas will always remain 2: 1, and the ratio of h2 gas to h2o gas will remain 1: 1 so if the gas volumes are measured at the same temperature and pressure: 44.8 liters of h2 + liters of o2 → liters of h2o

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.
