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.
