Redox potential

(Science: chemistry) The reducing/oxidizing power of a system measured by the potential at a hydrogen electrode. The ability of an electron to acts as a reducing or oxidising agent via its positive or negative charge.

Biochemistry

I have two true and false questions: 1) Electron from the reductant of a redox couple can transfer exergonically to the oxidized member of another couple that has a more positive standard reduction potential. What I think: At first I thought it is true, because from the equation: ...

Electron transport chain and DCPIP?

... it's electrons to and becomes reduced. then you need to look at the redox potential of complex III and complex IV, and DCPIP would be somewhere in between.

Electron transport chain and DCPIP?

... increase the rate of DCPIP reduction? Lastly how would i estimate the redox potential of DCPIP, what information would i need to do so? Any help would be grrrrreat!
