Yeah, the test is over but if majority of people thought the question wasn't fair enough, there may be some adjustment to the marking scheme. But I respect what you're saying!
p.s I believe the answer has to do with microsomes being able to protect newly synthesized proteins and that the proteins are moved directly into microsomes for protection. And the experiment was that the transport into the microsome happens co-translationally which refers directly to the same experiment on lecutre 4...rather than GPCR.
Anyway, I learned my lesson and hopefully I'll do better on the final exam.
