Questions about oxidative phosphorylation?

[scilearner]

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
