Questions about oxidative phosphorylation?

  1. Mar 2, 2011 #1
    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 :smile:
