What is the kinetic energy of the skiest a height of 50 meters above ground
29000 snits, because total energy remains on changes
80056 anittetuse toner remains unchanged
20000 units because total energy of the skier decreases
30.000 arts because tott energy of their decreases

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.
