Using the volumes of NBS solution you just entered and the average molarity of the NBS standard solution, calculate the milligrams of ascorbic acid in the 10.00 mL Vitamin C sample for each trial. Enter your calculated milligrams of ascorbic acid in the 10.00 mL Vitamin C sample, for each trial. Be sure to enter your calculated milligrams in the corresponding order that you entered your NBS volumes previously. The NBS volume you entered for entry #1 previously should correspond to the milligrams of ascorbic acid that you enter for entry #1 here. my volumes are: 8 ml, 8.5 ml, and 8 ml for vitamin C titration. my absorbic acid volume titrations are 13, 12.5, and 13. and my average molarity was .00177

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.
