How well do you know the electron transport chain? Iron-sulfur (Fe-S) proteins are essential components of the electron transport chain and play a critical role in oxidative phosphorylation. This DAT/OAT Biology question tests your understanding of non-heme iron in iron-sulfur proteins...

Many students confuse D/L notation with the direction of optical rotation. These are different concepts and should not be used interchangeably. Mastering amino acid stereochemistry is essential for success on the DAT and OAT. Understanding the underlying concepts—not just memorizing facts—will...

The D/L system is actually based on an amino acid's structural relationship to glyceraldehyde. Understanding this distinction is important for DAT Biology, Organic Chemistry, and Biochemistry. Can you explain why choice D is correct and why choice B is not? If you're preparing for the DAT...

A DAT organic chemistry and biochemistry crossover question involving dopamine synthesis and enzyme recognition. Many students memorize reaction names without understanding what is actually happening mechanistically. Here we are removing a carboxylic acid group and releasing carbon dioxide —...

Is it helpful to take biochemistry before the DAT? I have heard mixed things and my pre-health advisor isn't getting back to me (choosing classes soon).

Here’s today’s DAT Biology Question of the Day. The iodine–KI (Lugol’s) reagent is a classic lab test that shows up on the DAT, especially in questions involving biomolecules and food testing. Think carefully about what the reagent detects before jumping to an answer. 👉 Slide 1: Question 👉...

Wspp guys. I am testing May 2026 so I'm looking a bit far ahead, but I wanted to know how to go forward. I'll be graduating this Fall 2025 with all my prereqs for med school except Biochem and Orgo 2. Im taking an in person orgo 2 course offered at my local cc for that spring 26 semester but no...

I did my undergrad in Biochemistry and had a 3.94 GPA. I was doing research in AI Diagnostics and it really got me interested in the applications of CS in medicine. I decided to pursue an Ivy League master's in Computer Science and my GPA is 2.78 after my first semester and probably will be...

My school (UG) offers a 1 quarter biochem course which isn't as hard as the 2 quarter series biochem. I'm not confident in my ability to get an A in the series offering. The thing is, some dental schools ask for just 4 credits (1 quarter), while some ask for "Half-year". I don't know if 1...

I go to a community college and there are no other colleges/universities in my area (for at least 90+ miles). My college does not offer biochemistry! I am really frustrated since I know I could take it online at another university, but that doesn't look great for admissions from what I've heard...

I am heading into my last semester of undergrad. I am currently taking Cell Biochemistry this winter and I am scheduled for Biochemistry I in the spring semester. I am not sure if I need or should take the Biochemistry I class because my overall GPA is hovering at around 3.49 overall at the...

Hey everyone I’m a senior at my university and i took organic chemistry my freshman year and decided to take biochem now. My only problem is that i forgot a lot of the information for organic chem and barely remember how to name structures at the top of my head. I need to pass this biochem...

I had a practice question that read: "High levels of NADH will inhibit which of the following enzymes?" The answer choices Fructose 1-6-bisphosphatase and Glucose-6-phosphatase were both explained to be incorrect because: "This enzyme is required for gluconeogenesis. High levels of NADH would...

Hello there! One quick (and relatively insensitive) method to detect acute CO poisoning is to take a blood sample, dilute it and mix it with 5% NaOH. A pink tint in comparison with the colour obtained from a normal blood specimen (I've been told it'd be brown-ish?) suggests the presence of...

Last year I took a biochem/molecular biology course before I should have (chalk it up to poor advising and ignorance/ I had not taken the prerequisite course). This particular biochem course was also the course specifically for biochem majors, which I was not (i am ChemE). Anyway, I did not...

So I am in biochemistry right now and have my first exam in two days. A lot of the material is built off of prior orgo and gen chem knowledge, as this first exam is on amino acids, functional groups, pka curves, and hemoglobin/myoglobin saturation curves, however I just bombed my second quiz on...

I'm registered to take a 3 credit Intro to Biochem lecture, but I'm looking to add a lab in the future just in case I need it. The school I'm taking it at doesn't offer a lab at all. They're going to start offering a 4 credit Biochem course during the winter but it will still just be a lecture...

At my school I was unable to take the intro to biochemistry course (restricted to biochem majors) so instead I took a biology class considered the course equivalent. Is this enough to fill my biochem prereq or will I have to figure out how to take a course in the actual biochem dept?

Yes I know, I am 26 year old who will be starting post secondary education soon. I am almost always depressed about it. I will be older than most people in my class who will be in their 18s or 19s. Reason for being a Mature student, is that after dropping out of high school I was depressed, now...

Hey! We hope that you're all doing great. We've been working around the clock at the Physeo offices, and we're super excited to announce that after many thousands of hours, our complete biochem section is finally available on the website! This section is particularly unique and powerful...

Wondering which class to take between these two. Upper division Neuro course (good professor, however only two exams make up the grade. Not the best test taker, but an easy course) Biochem II (good professor, four exams (less weight on each exam), but would prob need a bit more study time...

Hey, guys! I'm selling the Examkrackers 10th Ed. MCAT Complete Study Package for $165 total or best offer. I will pay for shipping. The set is in almost like new condition. (There is no writing in any of the books and the only highlighting is on a few pages of the CARS book.) The books include...

Hello all, I am planning on taking the MCAT next summer (2019) and am trying to decide whether I should take bio 2 or biochem 2 before I take the MCAT. I have already completed all of the classes that are suggested to take before the MCAT, except for biology 2. The reason I am concerned about...

Hello, a few questions!! I am planning to take the March MCAT (I will be a second sem junior) so I have a little under 5 months to prepare. I am wondering what the best exam to take to find out my current standing is. I know that the AAMC materials are the best. Should I use the first exam as a...

Hello, Curious as to which one adcoms view as more important. The main core prerequisites or upper divisions? I know, I know, one must do well in all coursework and do the best they can. But when it comes down to it, do adcoms give a greater priority to upper divisions or core prerequisites ?

I’m a first year student.

I have taken Orgo 1 and 2 (8 credits). I did not take Biochem before I graduated :bang:. I'm a non-trad. On my AACOMAS primary, I selected "I'm not matching any course to this prerequisite" for Biochemistry, for the schools that require Biochem. I already submitted (9/12/18). I emailed a few...

As a general question in kinetics, when we are under LOW conditions of substrate, do we want HIGH or LOW affinity for the substrate? I have in my notes that when we are under low substrate conditions, we want low affinity for the substrate because we don't want to be using it up so much since...

Hello this is my first time posting on SDN. I'm a sophomore Biochemistry and Molecular Biology major (current GPA: 4.0) at a small liberal arts college, what I do: this is my second semester researching in a computational chemistry lab I am a volunteer ESL (English as a 2nd language) teacher...
