Uncouplers vs inhibitor

Web10 Dec 2024 · Uncouplers of Oxidative Phosphorylation: • Uncouplers can be defined as A substance that uncouples phosphorylation of ADP from electron transfer. • Uncoupling … An uncoupler or uncoupling agent is a molecule that disrupts oxidative phosphorylation in prokaryotes and mitochondria or photophosphorylation in chloroplasts and cyanobacteria by dissociating the reactions of ATP synthesis from the electron transport chain. The result is that the cell or mitochondrion expends energy to generate a proton-motive force, but the proton-motive force is dissipated before the ATP synthase can recapture this energy and use it to make ATP. Un…

They all act specifically, that is, each inhibitor binds a particular carrier or complex in the ETS. Irreversible inhibition results in a complete stoppage of respiration via the blocked pathway.
