FL 5 AAMC MCAT EXAM 20 24 What is the chemical structure of a component found in four of the five cofactors used by Na+ -
NQR? -Answer -says it is composed of flavin structure is a nucleotide base structure B could be structure C also could be structure D is an amino acid down betwe en B and C to help, look at the captioned note on the table. it says Fl represents flavin which is the redox active center in four of the five cofactors of Na+ -NQR C has an uniquinone AND HERE IS IS MENTIONED THAT UNIQUINONE IS IS A SUBSTATE What is the ra tio of cation to enzyme in the spectroelectrochemical experiments described in the passage? -Answer -cation : enzyme passage says Na+NQR was diluted to a final concentration of 0.75 mM in 0.150 molar of the cation ions cation .15 M: The reaction between NAD H 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? -
Answer -Conservation of energy, it is not created nor destroyed but merely changes forms A. Is not p ossible, Even if it was heat generation would be larger for a catalyzed rection. C. is impossible, reactants have to be close together to react The movement of a charged particle against its concentration gradient is energetically costly. Two open flasks I and II contain different volumes of the same liquid. Suppose that the pressure is measured at a point 10 cm below the surface of the liquid in each container. How will the pressures compare? -Answer -pressure=pgh g=10 p= density (same liquid so same densi ty) h= 10 cm both have same height so pressure will be the same -- if heights were different pressure would be different Question Which of the following substances is polar? -Answer -If there is a net dipole it is polar Question If all else is held constan t, which of the following changes would NOT double the volume of a gas? -Answer -pv=nrt What is the number of neutrons in the nucleus of the atom used to produce laser radiations? -
Answer -86Kr+ laser 86= mass Kr has proton number as 36 86-36=50 the cation or anion charge with any element is indicative of the charge aka electron count What is the molecular formula of the heterocyclic aromatic compound pyrrole? -Answer -passage says its a tetra pyrrole so there a re 4 carbons The radiation of wavelength 605 nm CANNOT be used to produce the fluorescence radiations depicted in Figure 3 because: -Answer -Maybe if you read the passage for once in your life and not get confident then maybe you wouldn't have to take the e xam for a third time Not D because look at the passage not C because of E=hc/lambda (high wavelength low energy) Approximately how many moles of Kr+ are contained in the laser tube at 0°C and 1 atm? -
Answer -Have to recognize STP conditions of 0 C and 1 at m (22.4 L) Volume in PV=nrt is in L 1cm^3=1mL The CD spectroscopy signal that was used to generate the data in Figure 1 arises from the chirality of the: -Answer -look for what is chiral B is not C is not D- most beta carbons are not chiral
