Porin-deficient mutant

Now suppose that the porin actually transports more than one substance - say, it can act on succinic acid as well as tetracycline. How might you figure out whether the porin is working or not? :)

Please help!

1. Sorry, I intended to type Oxaloacetate, not "Ox.-Aloacetate". 2. Sorry, I mistyped that, obviously succinic acid is C4H6O4. 3. Yes, succinate does pass electrons to Coenzyme Q (Q to QH2) but I thought you were referring to it entering "a stage" of oxidative ...

... sometimes acetyl, depending on the end compound that will be produced) after catabolism of pyruvate. 2) Yes, it is only the carboxyl group, C4O4 succinic acid has 6 hydrogen atoms. 3) Yes, oxidative phosphorylation, after a coupled reaction with Coenzyme Q to QH2 with the enzyme succinate dehydrogenase.
