let's say we will have acceptors A, B, C and D in reactions:
A -> B -> C -> D

say, we inhibit the second enzyme. In such case acceptors A and B would be reduced. If you inhibited the third enzyme, acceptors A, B and C would be reduced. My point is, that all the preceding acceptors will be reduced and all the consequent acceptors will be oxidised.

Similarly you will make it with your example ;)

Cis or trans? That's what matters.
