Describe how electron movement is related to the bonding in methane, ch4.
a) electrostatic sharing of electrons allows ionic bonds to form.
b) the atomic orbitals overlap and share electrons to form covalent bonds.
c) orbital overlap occurs between the atoms to exchange electrons and form the covalent bonds.
d) a transfer of electrons forms ions which are electrostatically attracted and constructs ionic bonds.

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.
