AAMC Section Bank: C/P #51 -- Is histidine + or 0?

Hello! My NSTP books, etc. say histidine is a positively-charged amino acid. But according to the AAMC's solution to this problem, at physiologic pH, histidine is neutral? I know that histidine's side-chain pKa and therefore overall pI make it borderline, but what should we consider histidine to be ...

AAMC FL 1&2 Chem/Phys

Hello! I have a few questions from the Chem/Physics sections of AAMC FL 1 and 2... Thank so much. ### AAMC FL 1 ### Chem/Physics >Question 10 I don’t really understand this. What’s a good general approach to this sort of question? I know why choice C is wrong — that is not participating in the react...

Re: NS FL3 C/P

Thanks, Yuqi! Very helpful. A few quick follow-ups: 18) This makes sense. In that case, for the MCAT, if we are asked about hybridization, should we only consider the structure as it appears and ignore resonance structures that aren't shown? 59) Makes sense! Regarding naming, I think my source of co...

NS FL3 C/P

Hello! I have two questions from NS FL3 C/P section. Question 18 I chose A because I learned to consider resonance when determining hybridization states, and if resonance is possible, to use the lowest hybridization state. I saw that the lone pair on the imine nitrogen could resonate up into a doubl...

AAMC Sample Test - Chem/Phys Section

Hello! I have a few questions from the Sample Test C/P section, which I figured I'd group together. Sorry for the several questions but hopefully they are not too hard to answer! Thank you! Question 11 I chose D, strong acid, because of the statement that the compound *completely dissolved* in water...

Question about NSTP FL Exams

Hello! I have already taken NS FL 1 & 2. Before I start taking AAMC FLs, I'm hoping to take one or two more NS FL tests, either as a FL in one sitting or more likely by breaking them up into one section per day. But I don't know which tests to choose from NS 3-10! Which one or two tests from among N...

Re: Trying to Stay on Schedule

If you reset the study plan, do you lose all of your progress, or does it just reschedule all of the material that's not yet marked as completed?

Re: Bio QPack Vol 1 Passage 4

Thanks, Mathias! Think it was just the intimidation factor. I think a learning for me is to be more attuned to novel concepts and appreciate the fact that some passages present new ideas within them that nevertheless leverage MCAT testable content.

Biochem Chapter 8 Test

Hello! I did pretty poorly on the passage-based questions in the Biochemistry end of chapter 8 test. I think I have a pretty strong understanding of the fundamentals of the CAC and ETC, but I think I had a hard time following the experiment in the passage and interpreting the implications of certain...
