How do Uncouplers affect electron transport chain and oxidative phosphorylation?

Uncouplers of oxidative phosphorylation in mitochondria inhibit the coupling between the electron transport and phosphorylation reactions and thus inhibit ATP synthesis without affecting the respiratory chain and ATP synthase (H(+)-ATPase).

Also asked, what is the difference between electron transport chain and oxidative phosphorylation?

Oxidative phosphorylation is a process involving a flow of electrons through the electron transport chain, a series of proteins and electron carriers within the mitochondrial membrane. This flow of electrons allows the electron transport chain to pump protons to one side of the mitochondrial membrane.

Also, what are the inhibitors of electron transport chain? The most important known inhibitors of the ETC are Amytal, Rotenone, Antimycin A, CO, Sodium Azide, and Cyanides.

Just so, what is the effect of DCCD to electron transport and oxidative phosphorylation?

Short answer: In the electron transport chains (ETC) of both photosynthesis (chloroplasts) and cellular respiration (mitochondria), DCCD (a toxin named dicyclohexylcarbodiimide),has been shown to inhibit the ETC “proton pumps,” which in both cases directly affects ATP synthesis.

How do Uncouplers affect cellular respiration?

Some uncoupling is favorable for the energy-conserving function of cellular respiration. In oxidative phosphorylation, leaks cause a certain uncoupling of two consecutive pumps, such as electron transport and ATP synthase, and may be described as the membrane potential-driven backflow of protons across the bilayer.
