Hello everyone,

This is an area I don't understand much, so I have some questions.

*Uncouplers of oxidative phosphorylation (these are true/false questions)
-make respiration uncontrolled
(I know it is true an it has something to do with ADP no longer controling respiration , but I really don't understand the question much)
-Increase the permeability of the inner mitochondrial membrane to proteins
(I'm thinking true. Is this how they disspiate the hydrogen gradient)
-Increase respiratory rate (Don't know)

Also how does 2,4 DNP acts, does it inihibit a complex, or move hydrogen ions disturbing the gradient?

Also more questions
-Electrons can be transported as H atoms in the electron transport chain?
(I'm assuming false, as it the energy from electrons used to push Hydrogen ions out)
-Ubiquionene is a mobile electron carrier.
(But isn't ubiquinol the reduced form that acts as the carrier)

Thanks a lot
