Question
Which of the following could operate as an electron transport and ATP synthesis un coupler?
- TheFo base-piece of ATP synthase
- Dinitrophenol
- Neither (a) nor (b)
- Both (a) and (b)
Hint:
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named 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.
The correct answer is: Both (a) and (b)
TheFo base-piece of ATP synthase and Dinitrophenol could operate as electron transport and ATP synthesis un coupler.
