Answer :

Everything upstream of Cyt-b would accumulate in their reduced state

Now antimycin A, via inhibiting cytochrome B prevents the proton transport, as a result, the PMF isn't always advanced in the first place. ie., there may be no proton gradient at all as a result, ATP synthesis is blocked.

the binding of antibody to subunit VII inhibits the transfer of electrons to cytochrome b-566. consequently, two electrons are transferred to the iron-sulfur protein and cytochrome c1 through an antimycin-insensitive pathway.

Cytochrome b (Cytb) is one of the three proteins encoded by way of the mitochondrial genome of Plasmodium species [20]. As part of the cytochrome bc1 complicated (or complicated III) (parent three.2), Cytb is an critical aspect of the mitochondrial electron transport chain (etc).
