If we had a 17 carbon fatty acid we would get 8 acetyl coa that would follow 7 rounds of beta oxidation + 1 propionyl coa Each round of oxidation yields 1 NADH and 1FADH2 (4ATP/round) => 4*7 rounds = 28ATP Activation -2 ATP 8 acetylcoa => 8 rounds of TCA and each round = 10 ATP so => 80 ATP...

The TL;DR version is in bold. Thanks! ISSUE 1: According to the TBR Biology part 2 book (section 7 - Metabolic Pathways; p. 195 in the newest edition - copyrighted 2016), oxalosuccinate is a beta-keto acid. In fact, the TBR book doesn't even call it oxalosuccinate (or oxalosuccinic acid); they...

Complex I results in oxidation of NADH to NAD+ and two electrons flow from the mitochondria matrix to the complex that is embedded in the inner membrane of the mitochondria. I am trying to find an explanation to why 4H+ are pumped to the intermembrane space. Is it because electrons left the...

I am confused because my biochemistry notes say that citrate synthase is the rate limiting step and the kaplan book says that isocitrate dehydrogenase is the rate limiting step of the TCA. Which one is the correct one? Thanks

Hi! I had two questions: 1- 2,3 BPG allosterically binds to Hemoglobin changing it to its T state so it has lower affinity for oxygen. I am confused on how the percent saturation of oxygen in the lungs is still able to reach 100% if Hb cannot bind to oxygen as readily? 2- Since fetal...

- How come glut2 is said to be insulin independent if it senses the release of insulin to store glut2 in hepatocytes? - I understand that glut4 has a Km similar to the concentration of glucose so it gets saturated fast but how come glucose influx can still occur if the glut4 receptors are...

any idea?

So I'm a biochemistry major and most of my classes are biochem classes. I'm assuming that they will be added to my science GPA on my application, but will it be added to biology or chemistry?

So here are the facts: I'm a senior majoring in biochemistry. I always wanted to apply to med school but my hesitation is my GPA. Right now I have a 3.65 overall. The reason that it's so low is because I was originally majoring in biomedical engineering. Fall semester of my sophomore year, I...

I was planning to take a gap year, but the closer it gets the more I just want to go straight to medical school. I am a year behind in chemistry, meaning I am finishing up ochem as a junior. I need biochemistry before I can take the MCAT, and it is offered as a 6-week summer course at my...

I am a senior biochemistry student graduating in May with an anticipated GPA of 3.3. I also just graduated paramedic school which I did at another school but simultaneous to my college studies. Throughout all of this, I have worked part time for two years now as an EMT in the city near my school...

hi all, I think I have a peculiar question. I am from the Engineering background and my undergrad GPA is not that great although the cumulative comes to around 3.2. been working for about 2.5 years in total between my bachelor's & masters and afterwards added (probably a unique situation, for...

I am a first year psychology student at UTM, and I am in the process of making my 4 year plan. I was a little bit worried about fulfilling pre-requisite courses throughout my degree as I hope to be accepted into the "Behaviour, Genetics, and Neurobiology" specialist program, however I have...

Hey! I found out only too late that the biochemistry course I took in my undergrad doesn't count toward KCUMB's 3 semester hour biochemistry requirement. I looked at 2 community colleges near me and neither seem to offer it, and applying to the local university would cost nearly 1,000$ for just...

Hi, I know there are a few of these questions on the forum, but I had a question sort of specific to my own: I don't have a stellar GPA(~3.2) at the moment and am struggling financially as well. And I just transferred to a 4yr university. I am given two choices: Biochem major with Bio double...

Hello everyone, I am a current Biochem. undergrad student and I got into this career just because I like chemistry. I am a junior now, and I still don't know what I want to do after my undergrad. I don't even know my options. I know this is a very vague and a stupid question, but can someone...

I know there have been some posts about this but they really weren't clear responses to me. Anyone who has actually taken it, can you let me know the set up are their quizzes before the final exam or practice questions, is it difficult...any advice on taking the course?? thanks a bunch

So as of right now I'm taking my DAT this summer, doing a one-year SMP next academic year, and then applying next summer. Can I apply before having taken biochemistry in the summer of 2017, and just take biochemistry by itself the fall of 2017 during when I'm applying? I'm looking to get...

I'm finishing organic chemistry this quarter and will be taking biochemistry in the fall. Looking back, I know general principles of reactions (E2, E1, Sn1, Sn2, tetrahedral intermediates, etc.), but I don't remember certain reaction mechanisms. On top of that, for other reactions where we never...

So I am currently completing my Bachelor in BioChemistry, and I have no idea what to do once I graduate. I am definitely considering going to graduate school, because there is not many good jobs just with a Bachelor's alone. I am thinking about pharmacy, I just will have to take a couple extra...

Hi! I have heard a lot of mixed things as to what courses are sufficient in preparing you for the biology section of the DAT. Initially, I thought that the content of gen bio 1 & 2 would be enough to prepare me; however, I've heard that courses such as biochemistry, immunology, and anatomy are...

Has anyone taken the online Biochemistry course at the University of Florida or Colorado State University? I am specifically interested in the one at Florida, but want to hear opinions! Thanks!

So, I just registered for the Kaplan in-person MCAT prep. I currently have access to prep materials like Kaplan ebooks, practice questions, the flashcard app, and the MCAT channel. Actual classes start May 25th and end July 27th, there are 12 sessions. I would like to begin studying as soon as...

Hello, since beginning undergrad I've been interested in MD/PhD, but due to the competitiveness of the MSTP programs I have always been concerned about the viability of these plans. Now that I'm applying in a month, I've done a lot of self reflection and I'm going to try to apply to some...

Anybody do the Khan Academy passage called https://www.khanacademy.org/test-prep/mcat/biological-sciences-practice/biological-sciences-practice-tut/e/the-role-of-alcohol-abuse-in-pancreatitis I had a question regarding the answer to this question

I am just trying to get an overall idea of Acetyl CoA and how it effects the different pathways. Here is what I know so far: When cells need ATP, Glucose-->Pyruvate-->Acetyl CoA-->ATP When cells have met energy needs There is a buildup of Acetyl CoA which, inhibits Pyruvate Dehydrogenase...

Hi Everyone, I have already been accepted to medical school and will start this fall. However, I need to complete an online biochemistry requirement (accredited with biology and o.chem as a prereq). Does anyone know the cheapest priced one? Thank you!

I plan on self-studying for the MCAT this summer for the September exam with a 4 month schedule using mostly TBR material. I'm also taking a summer biochem course that meets 4 times a week for 6 weeks (each class is 2 hours long) and for the second half of the summer, I'll be taking a lab class...

I purchased the latest edition of the Examkrackers 1001 series in the summer of 2013 (I'll come back later and update the exact edition once I check). I am wondering how useful they will still be for the new MCAT, particularly in relations to biochemistry since that is the subject that has...

Kaplan considers Cysteine to be polar while I have read in my Cell Bio book that cysteine is nonpolar. Does anybody know what AAMC considers Cysteine to be classified under? Which brings me to my next question. When 2 cysteines come together to form a disulfide linkage, why do they form a...

Hi, so I'm currently a junior and I'm applying this June. I took all the required classes except for biochemistry, which I was planning to take it in Fall quarter of my senior year. Will taking biochem after applying affect my chances of admission to dental school? Will it delay any interviews...
