    MCAT Study 2015 TBR/ TPR/ EC and NS

    Hi All! 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...

    Fatty acid oxidation of an odd number

    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...

    2,3 BPG and lung oxygen saturation

    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...

    Why is it that dipeptides and tripeptides can be absorbed in the intestinal wall but disaccharides have to be broken down to monosaccharides to be absorbed? Thank you!

    Pulmonary surfactant and lung collapse

    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...

    Nodes of Ranvier

    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...

    MCAT I am behind

    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...

    TBR forces and torque

    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...

    Magnetic field TBR

    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...

    Electrostatics TBR

    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...

    Mass spectrometer radius curvature

    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? Thanks!

    Electrostatics TBR

    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...

    TBR light that hits an interface in a perpendicular fashion

    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...

    Geometric Optics question TBR

    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...

    Higher wavelength penetrate the tissue better why?

    Why does a higher wavelength penetrate a tissue below the skin better? Why wouldn't it be a lower wavelength => higher energy that penetrates a tissue better? Thanks!

    Diffraction Interference

    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!

    Shock waves Physics sound

    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? Thanks!

    What do you think?

    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...
