below. Some chemical factories make hydrogen gas (Hz) using a process called steam methane reforming. In this process, methane (CH4) combines with steam (H20) at high temperatures to form a mixture of hydrogen gas and carbon monoxide (CO). This mixture can then be used to make substances like hydrogen fuel and ammonia. In the chemical reaction described in the passage, which of the following are reactants?

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.
