Oxidative phosphorylation is basically a way of oxidising reduced hydrogen carriers (NADH and FADH2) back to their oxidised forms (NAD+ and FAD) by using molecular oxygen to convert the hydrogens to water.
NADH + H+ + ½ O2 + 3ADP + 3Pi → NAD+ + H2O + 3ATP
FADH2 + ½ O2 + 2ADP + 2Pi → NAD+ + H2O + 2ATP
FADH2 + ½ O2 + 2ADP + 2Pi → NAD+ + H2O + 2ATP
In eukaryotic cells oxidative phosphorylation takes place in the organelles known as mitochondria (singular: mitochondrion).
Oligomycin, an antibiotic, acts by binding ATP synthase in such a way as to block the proton channel. That is the mechanism by which oligomycin inhibits oxidative phosphorylation.
