RNAS C Practice Test Review 437 Questions with Verified Answers A capacitor and resisitor in parallel - CORRECT ANSWER will have same voltage across since in parallel. if in series, voltage drops would occur they can be treated together If the absolute pressure of a gas is increased from 3 atm to 4 atm at constant volume, then the absolute temperature of the gas will increase by: A. 25%. B. 33%. C. 67%. D. 75% - CORRECT ANSWER B. Assuming the validity of the Ideal-Gas law, PV = n...

MCAT PRACTICE QUESTIONSprimary structure of basic protein is formed when - correct answer the amino acid terminus of one amino acid attacks the carboxy terminus of another what amino acid is the only one without a chiral center therefore is not optically active - correct answer glycine you can tell if it all contains glycine when you know under polarized light to determine if the whole acid is optically active or not product of grignard reagent - correct answer new cc bonds the eye cann...

What is the general formula for a carbohydrate? - Cx(H2O)y How do you determine the number of stereoisomers for a given carbohydrate? - 2^n where n= number of stereocenters Distinguish between the D and L designations for carbohydrates. - In the L form the hydroxy group is on the bottom left closest to the CH2OH group in the frame of a Fischer projection In the D form the OH is on the bottom right What are anomers? - Diastereomers formed by the cyclization of carbohydrates (*note they ...

agarose and agar correct answer: polysaccharides used to run DNA gels and for microbial plates bacterial cell walls correct answer: contain polysaccharides in their peptidoglycan layer lectins correct answer: are proteins that bind to sugars protein glycolsylation correct answer: assists in folding and cellular recognition, e.g. ABO blood groups -ose correct answer: indicates a molecule is some kind of carb blood group antigens correct answer: glycoproteins containing differ...

Primary function of carbohydrates - Fuel for body - energy and biosynthesis Classification of carbohydrates - - aldoses vs ketoses - number of carbons (ex: triose = 3 carbons) Constitutional isomers - same molecular formula, different connectivity Stereoisomers - Compounds with the same structural formula but with a different arrangement of the atoms in space. Enantiomers - mirror images of each other Distereomers - stereoisomers that are not mirror images Epimers - differ in ...

Formula for possible stereoisomers - correct answer 2^n If Q > Ksp.... - correct answer Precipitate will form Which way do electric field lines point? - correct answer Exit from positive and enter at negative Reducing sugar - correct answer Sugars which undergo mutorotation, in which the process of ring opening occrus at the hemiacetal group, and the intermediate is a aldehyde Fatty acid structure - correct answer Consists of hydrocarbon tail and carboxylic acid What ...

(III) Differences between the right and left ventricle of the heart - Answer-Right ventricle: feeds pulmonary circulation; generates less force and faces less resistance (bc circulation is much shorter) Left ventricle: feeds systemic circulation, generates more force and faces more resistance (bc longer circulation) (III) In an electric field (such as one that would be used in SDS PAGE), what charges are the anodes and cathodes? - Answer-Anode: positively charged Cathode: negatively charg...

MCAT Organic Functional Groupsalkane - correct answer alkene - correct answer alkyne - correct answer alkyl halide - correct answer alcohol - correct answer thiol - correct answer ether - correct answer oxirane (epoxide) - correct answer phenol - correct answer aldehyde - correct answer ketone - correct answer hemiacetal - correct answer acetal - correct answer ( not H, but another R) so R1, R2, OR1, OR2
