Re: NS Ochem Qbank #3, #30

A bit of core MCAT strategy: Read the question very carefully. Reading questions is literally more important than knowing things! [...] a reason why ESI should NOT be used to obtain data about transmembrane proteins in their native state? This says that the question asks us not about what would be g...

Re: Ochem Qbank #3, numbers 28 and 33

Yes. It's deprotonated, or really it's deuterated. As in, there is only one proton and trillions of deuterons jumping on and off the carboxylate rapidly. And if calculus taught me anything it's that 1/lots=0, so you are right there really isn't a proton there anymore at all, ever. The MCAT almost al...

Re: Course book (pg. 125 - ankle diagram)

After some head-scratching, the problem in this case is that you would need a lot of new information and you would be essentially answering a new kind of question. Which really just means that the original prompt lacks a little bit of specificity: It should tell us which equilibria it wants us to co...

Re: Ochem Qbank #3, numbers 28 and 33

You have a sharp eye for trouble! So it turns out they are both correct. Wait! What? For 28, the question will in the future either specify to only consider the integration environment of protons attached to carbon atoms, or simplify the chemical species in question. For 33, a deuterated solvent wil...

Re: PS FL 6 Q 58

You have a point here, this question has more than a few problems. It may have escaped detection for this long due to it's position at the end of an FL. Either way, this discrete is being replaced. The replacement question will be testing the same content and foundational skills, but will be much mo...

Re: NS FL6 - psych/soc question 7

Hey, that's a good catch, EXS091! There is actually a little inconsistency in the explanation text and nowhere could you have gleaned that from the passage. The explanation text will soon be adjusted to the passage text (L3 = Llead and L4 = Rlead). There is also a small error in the labeling of the ...
