Re: NS FL 9 CP Q25

Significance is ultimately an arbitrary threshold. A discussion of how to create a reasonable cutoff is very, very far beyond the scope of the MCAT or the time and space we have here.

Re: NS FL 10 BB Q8

First: No need to overthink excess/lack of. These terms simply mean in comparison to physiological concentrations, which are fixed values that we have observed in the organism being discussed. Second: For now, discard this question entirely. After some review of the literature, I can safely say that...

Re: NS FL 10 P/C Q30

Regarding the book: Yes, those descriptions are correct. It is however explaining the whole system of how an antioxidant molecule works, including how it is regenerated. Notice that this is why the text describes a lot of redox pairs! Once for example G-S-H acts as an antioxidant, it itself is the m...

Re: NS FL 10 P/C Q30

Hahaha the trick answer will be to say ubiquinol but that isn't true either because when it gains the electrons it also gains the hydrogen in the alcohols which is why the molecule remains uncharged. ( you wanted to play with my mind lol) but I can still see why this molecule could act as an antiox...

Re: 108 CARS Passages (Section2, Passage4, Q20, P49)

Hey there, I'm always happy to help! You are right that the explanation isn't the most helpful possible, possibly even a tiny bit inconsistent. This is a question asking about which statements the author would (or might) agree with and which he would CERTAINLY not. In answer choice C, we are given s...

Re: NS FL 10 P/C Q30

Oxidation is the loss of electrons from a species, reduction is the gain of electrons in a particular species. So while NADH itself is indeed most likely to be oxidized, when it does so, it will reduce some substrate. Likewise, the reduction of NAD+ to NADH is guaranteed to be oxidizing something el...

Re: SB C/P Q4 and 8

#5: Just the definition of power, or what we can call the power-energy relationship: Power = E/t =W/t Power is the rate at which you are doing work. Therefore, Power * time = energy. Try out both lasers and see what pops out! #8: This is possibly my all-time favorite from the section bank for reason...

Re: MCAT Lesson Course Book

You definitely do get a copy of the book in the mail.

You already seem aware of this, but you can take a look at the *.pdf version of the book ahead of time here.

Re: NS FL 9 P/S Q48

Most importantly: This question wants you to use the data provided in the text, and only the first of the 4 graphs in figure 1. The other graphs are not at all useful in answering this question. The explanation given in the material has a small mathematical flaw: Disproportionate increases over the ...
