Setting Up the Heating Experiment (continued) Heating Experiment Data Table Observe as the air temperature of Cup 1 and Cup 2 is measured. Record the temperature data in the table.
Starting air temperature (oC) (before lamp is turned on)
Final air temperature (oC) (20 minutes after lamp is turned on)
Change in air temperature (oC) (final temperature minus starting temperature)
Cup 1
(air above surface)
Cup 2
(air, no surface underneath)

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.
