The decarboxylation of oxaloacetate into pyruvate and CO2 at pH 5 and 25C is 10% complete in 5 s, 44% complete in 25 s, 58% complete in 38 s, and 90% complete in 100 s. What is the reaction order with respect to oxalacetate and the rate constant (including units) for the reaction? Show your work.

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.
