Amedical cyclotron used in the production of medical isotopes accelerates protons to 6.5 mev. the magnetic field in the cyclotron is 1.8 t . a proton exits the cyclotron 1.0 ms after starting its spiral trajectory in the center of the cyclotron. how many orbits does the proton complete during this 1.0 ms? show your calculations!

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.
