Hi guys,

So on AAMC 4, question 128, there's a question of what happens if:
- B suppresses A
- A is continually synthesized
- B is added to SATURATING CONCENTRATION

I thought that when it's at saturating concentration, that means adding more of B won't matter because its effect is maxed out. And since A is continually synthesized, I thought the overall effect would be that A is functioning normally.

The answer, however, is that A is completely suppressed because of B. Do I misunderstand "saturating concentration?"

Thanks!

i'm guessing by "suppressing" you mean B binds to A to make A nonfunctional. In that case, for B to continually be saturated in solution, all of A needs to be bound to B. Thus, A is nonfunctional.

I don't have access to AAMCs anymore to be sure.
