AAMC Question and Certified Solutions 2023/2024 The ATP-dependent phosphorylation of a protein target is catalyzed by which class of enzyme? - correct answer Transferase Oxidoreductase enzymes - correct answer Oxidoreductases catalyze oxidation reduction reactions. At least one substrate becomes oxidized and at least one substrate becomes reduced. Transferase enzymes - correct answer Transferases catalyze group transfer reactions- the transfer of a functional group from one molecule to another (kinases require ATP) Hydrolase - correct answer general term for enzymes that catalyze a hydrolytic cleavage reaction Ligase enzyme - correct answer Join DNA fragments Which of the two products was detected during the experiment? Compound 2a; it has three aromatic rings. Compound 2a; it is a diphenol. Compound 2b; it has extensive delocalization of electrons. Compound 2b; it is a mixed phenol and quinone. - correct answer This is an Organic Chemistry question that falls under the content category "How light and sound interact with matter." The answer to this question is C because Compound 2b has a much larger set of conjugated double bonds than Compound 2a. In the passage it was stated that Compound 1 was chosen as a substrate since it gave rise to an equilibrium mixture of products, one of which was intensely colored. It is a Reasoning about the Design and Execution of Research question because you are asked to reason about the features of a research study. What produces color in a chemical structure? - correct answer conjugation Kcat = Vmax/ [Etotal] - correct answer catalytic efficiency equation - correct answer Kcat/Km the bond that links monosaccharides together in an oligosaccharide is a special type of acetal linkage known as a.... - correct answer glycoside bond Kapp is the apparant affinity constant under the condition that you have a second substrate - correct answer kcat is used to describe the rate-limiting step of catalysis under saturating conditions of substrate - correct answer When experiments are performed on enzymes that display traditional Michaelis-Menten kinetics, what shape does the graph of V0 versus substrate concentration [S] have? - correct answer A hyperbolic dependence on [S] Color, wavelength, frequency - correct answer Pauli Exclusion Principle - correct answer An atomic orbital may describe at most two electrons, each with opposite spin direction law of mass action - correct answer The rate of a chemical reaction is proportional to the product of the concentrations of the reactants Henry's Law - correct answer the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid
