You are camping and it is time to build a campfire. You gather logs and stack them loosely, and then you add small twigs and leaves to make the fire easy to light. As you sit by the fire, the logs burn bright in the darkness, and you feel the heat coming toward you.
Which of these statements are true about the amount of energy transformed in the campfire? Choose the two that apply.
A. The Law of Conservation of Energy applies to these transformations.
B. The chemical energy in the logs is lost during the transformation.
C. The fire is hotter than the logs were, so energy is gained in this transformation.
D. The amount of heat and light energy released equals the amount of chemical energy that is burned.

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.
