Im preparing to study for the mcat this summer. I'm going to do an independent study following Snd study plan or MCATjelly. If you have the books for these in a set please let me know. Im looking to but some books for cheap. I would prefer there to be no writing. I will except pencil...
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...
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...
I had a question on pulmonary collapse and surfactants
I know that surfactants reduce the surface tension of the alveoli fluid because by adding the surfactant the hydrophilic molecules are able to move away underneath this surfactant if we apply a force and therefore they aren't that resistant...
I am trying to understand why the myelin sheaths would make a difference in conduction
- I know that the axon is long so since L is proportional to resistance then the electrical current will dissipate in long distances
- If we add myelin sheaths the Area will increase so the resistance will...

I have been studying for the MCAT and taking 18 units at the same time. So far, I have finished chemistry content review and still have 3 chapter of physics TBR. I haven't done bio or biochem or psych and my MCAT is on March 31st. What should I do ? I am completely screwed? I can't reschedule...
The question asks: "If a person starts at the rim of a spinning platform and is pushed radially toward the central axis by a moving exterior wall, then what happens to the normal force felt by that person due to the wall?"
Answer is: "It decreases, since r decreases"
I used a= v^2/r but TBR...
A laboratory pan balance is shown
In general when calculating the mass of the pan neglecting the mass of the rod:
A- is possible if the fulcrum is placed at the center of mass of the whole balance
B- is possible if the center of mass of the rod is the pivot point
C- is not possible
Assuming all factors affecting wind resistance to be equal except shape which of the following shapes would generate the greatest terminal velocity in the experiment
a- a water droplet
b- a sphere
c- a cylinder
d- a cube
answer is A and the answer says that during free fall a liquid will...
This is a question from TBR translational motion Phase II
If all 4 objects were launched from a cannon mounted at a 45 degree angle what would be observed?
I. Object I would have the greatest range
II. Object IV would have the lowest velocity upon impact of the ground
III. The object...
An electron enters an uniform magnetic field and travels at right angles to the field in a circular path. As the particle moves the magnetic field
A- does not change the velocity of the electron
B- slows the electron down
C- speeds the electron up
D- does not changed the speed of the electron...
It's a cathode ray tube - It's the Electrostatics chapter, passage X, Q.65 (P 149).
On occasion, the electrons are made to pass through the plates undeflected. If the electrons enter the region between the plates with the same direction, but with excessive velocity:
A) they will be deflected...
help me get into med school please
If the voltage across the plates were reversed what would happen to the oil drops between the plates from the Millikan oil droplet experiment?
A- They would accelerate upward
B- They would accelerate downward
C- They would move with constant velocity upward
D- They would move with constant...
Hello. I am a freshman right now. I have joined several clubs, etc. Was wondering what other kind of stuff I should do? I posted a thread similar to this a couple months ago and I got a couple A-s and ONE B+ -_- I know this doesn't kill my chances and I'm doing really well right now. I am...
How come a particle with larger mass has a greater radius of curvature? I know that the equation shows that r= mv/qB so if m increases r increases but if a particle is heavier it deflects less so shouldn't the radius of curvature be smaller?
The dielectric constant K of an unknown material is measured as a function of temperature. What can explain the sharp rise and subsequent slow decay of K as the temperature increases?
Graph is K vs T : it has a sharp increase at T1 and then starts to decrease
A- The solid material melts at T1...
We are given a figure of a half-cylinder with a point a at the top of the half cylinder. Light is transmitted through a half cylinder and the beam was allowed to strike a semi-circular screen.
Question asks : Light that initiates from point a in the figure:
A- will always strike the middle of...
Which of the following statements are true about the index of refraction of a substance?
I- it is inversely proportional to the speed of light in the substance
II- it depends on the properties of the substance
III- it depends on the radius of curvature of the substance
IV- It can have a value...
I had some questions on this topic:
1- Is diffraction the same as interference?
2- why does the slit size have to be comparable or smaller than the wavelength? and is it the case for single slit and double slit?
Thanks a lot!
Passage says " The 4 strings of a violin all have the same length of roughly 12 inches. in an experiment students studied the 4 strings of an old violin and the four strings produced these frequencies
string I : 196 Hz
string II: 294Hz
string III: 440 Hz
string IV: 659 Hz
The question asks "...
I am studying from TBR and I'm not sure I understand what the shock wave is. I know that shock waves occur when vobject > vsound but I don't understand what's happening to the pressure why is it increasing and then decreasing?
Hi can someone help me with this question please!
It's a passage but I will type out the part that we need:
they gave us a circuit with a power supply- a resistor R1 and a capacitor with a solution of cell suspended in a solution known as a dielectric constant: they are talking about...
I am looking for reviews or references for the program run by Leah at Leah4Sci.com. She gives a TON of free resources that I find very helpful as she has a way of breaking down topics that is clear and easy to follow.
I took the MCAT this past October and scored below average :( In...

So Im currently in my first week Senior year at University. Before starting this semester I had plans on taking 15 credits this fall, allowing me to have enough time (20hr/week) to study for the MCAT. Now looking at my syllabus for my 4 courses (+one internship and 2 part time...
1) Composite score: 509 (82nd percentile) PS: 127 CARS: 127 BS: 128 Psych: 127
2) Practice Test: I took Kaplan FL exams and the official AAMC scored. I took the exam twice, once in January and once in May. I was hoping to hit it on the first shot but I fell into pitfalls the 1st time around...
So I was hoping to get some other opinions on this because I'm feeling overwhelmed at this point.
I took my kaplan tests all out of whack for who knows why, but anyway here they are in this order:
Pretty crazy how I can drop 10 points...
So I am near finishing the CARS S&P book and towards the end of the book, and I've been scoring consistently around 70% on the last 7 passages (which is a huge boost from what I was scoring in the beginning of the book)
I was wondering what difficulty level for the passages in CARS...
Hey guys! I'm kind of new to posting on studentdoctor but I was hoping to gain some insight. I was wondering what journals/ books you guys have found to help with speed/ efficiency of reading. I am using Kaplan and have seen significant improvements in my scores over the past few weeks, however...

I am working on a site to compile all the free MCAT material I can find so students can have a place to go if they cannot afford a commercial MCAT class. The site is in beta testing right now and I come to you all for advice and testing! Please give the site a look through...
I recently took the MCAT and have yet to receive my score. However, this was my third attempt and I have been putting a lot of pressure on myself post exam and I begin to think of questions that I got wrong. My first MCAT was on the old version, which I scored a 22. I did very little prep and...
