Oligomycin, an antibiotic, acts by binding ATP synthase and
blocking the proton channel. What would be expected to happen to
the H+ gradient with the introduction of oligomyciin?

a) H⁺ would begin to flow from the intermembrane
space into the matrix back through the proton pump complexes of the
ETC.

b) The H⁺ gradient would be unaffected.

c) The buildup of H⁺ in the intermembrane space would
eventually overcome oligomycin and ATP would continue to be
generated.

d) H⁺ would stop being pumped from the matrix into
the intermembrane space.
