AAMC Exam 4 FL ReviewLimestone does NOT decompose when heated to 900 K because, at 900 K, ΔH is: A. positive and less than TΔS. B. positive and greater than TΔS. C. negative and less than TΔS. D. negative and greater than TΔS. - correct answer B. positive and greater than TΔS., the reaction does not occur, ΔG = ΔH - TΔS > 0. From inspection of the reaction, it can be concluded that ΔS > 0 (a gas evolves). Consequently, ΔH > TΔS explains why the reaction does not occ...

AAMC FL 5 C/P *What quantity of Compound 1 must be provided to prepare 100.00 mL of solution with a concentration equal to Ki? A. 48.4 mg B. 24.2 mg C. 5.64 mg D. 2.92 mg "Compound 1 (molar mass: 483.5 g/mol) has been shown to inhibit HIV-1 protease with Ki = 60.3 μM (Table 1). Ki is the dissociation constant for the enzyme-bound inhibitor, which is either EI or ESI, depending on the type of inhibitor." - correct answer D In 100.00 mL solution, 60.3 μM Compound 1 contains 6.03 μm...

AAMC FL 5 CHM/PHYSwhat can increase solubility adding a lone pair structure of flavin The reaction between NADH and ubiquinone is exergonic, but the reaction, when catalyzed by Na+-NQR, does not generate much heat in vivo. What factor accounts for this difference? The reaction catalyzed by Na+-NQR in vivo: ANS: is coupled to the movement of a charged particle against a concentration gradient. WHY: The movement of a charged particle against its concentration gradient is ener...

AAMC FL 5 REVIEW The association observed experimentally between the expression of miRNAs and mRNAs in AR kidney transplants indicates that miRNAs regulate the expression of genes implicated in which type(s) of immune response(s)? A. Adaptive immunity only B. Humoral immunity only C. Innate and cell-mediated immunity only D. Adaptive and innate immunity only - correct answer The passage shows data for the strains that are affected to contains B and T cells. B cells are for humoral immun...

AAMC FL 5Question 6 Thought process: - Didn't know the structure of flavin, therefore needed to narrow down answer from answer choices: - Knew A was a pyrimidine, cross that out - Had not seen structure of B before - Knew C was ubiquinone (still chose just because ubiquinone was mentioned in the passage (stupid)) - Didn't try and analyze structure of D at the time Correct thought process: - Cross out A bc pyrimidine - Never seen B before (come back to later) - Cross out C because u...
