According to the collision theory, which is required for a high number of effective collisions? a very low amount of force from colliding molecules a very low amount of kinetic energy from colliding molecules molecular collisions that have very specific orientations molecular collisions with energy to overcome activation energy

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.
