1. Which of the following best describes a similarity in how rotenone, cyanide, and carbon monoxide exert their effects?
a. The poisons prevent glucose from being oxidized into pyruvate, consequently reducing the amount of
high-energy electrons available to the electron transport chain
b. The poisons block the entry of hydrogen ions into the enzyme that phosphorylates ADP
The poisons inhibit the pumping of hydrogen ions across the membrane, thus disrupting the
electrochemical gradient and chemiosmosis
d. The poisons increase the reduction of oxygen to water, resulting in plasmolysis of the matrix
C.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
