Q165
The Respiratory uncouplers
A.
Inhibit ATP synthesis
B.
Disrupt electrochemical potential gradient
C.
Hamper membrane permeability
D.
All of the above
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
An uncoupler or uncoupling agent is a molecule that disrupts oxidative phosphorylation in prokaryotes and mitochondria or photophosphorylation in chloroplasts by dissociating the reactions of ATP synthesis from the electron transport chain. Uncouplers are capable of transporting protons through mitochondria and lipid membranes. It also disrupts the electrochemical potential gradient.
