III. If a hypothetical molecule were to prevent Plastoquinone from diffusing H+ to the thylakoid lumen, what would happen to the level of oxygen released as a byproduct
IV. If a hypothetical molecule were to steal electrons from Cytochrome complex at the same rate that DCPIP does from Plastoquinone, what would happend to the level of oxygen released as a byproduct?
Homework Answers
III) the levels of oxygen shall reduce. Thai is because H+ from water will not be used to liberate oxygen.
IV) the levels of oxygen shall increase. This is because electrons shall be drawn from water at a higher rate and so more and more oxygen shall be released.

Inhibitors of Oxidative Phosphorylation The following chemicals inhibit oxidative phosphorylation: Cyanide: Cyanide is a naturally occurring compound that binds to protein complex IV of the mitochondrial electron transport chain and prevents transfer of electrons from the protein. Metformin: At the cellular level, chemically synthesized metformin, a drug commonly prescribed for Type 2 diabetes, inhibits mitochondrial respiration by blocking complex I.
