Now it's time to make dinner. On the menu tonight are fried chicken, green beans and cornbread. (5) The first thing you need to do is turn on the burners so that you can fry the chicken and boil the water for green beans. You have a natural-gas (methane, CH4) stove. When you ignite a natural gas stove, the methane reacts with oxygen (O2) to produce carbon dioxide and water vapor. The reaction is CH4 + O2 > CO2 + H2O. Explain what type of reaction this is.

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.
