BIOCHEM RUTGERS CORRECT TEST PAPER
QUESTIONS AND ANSWERS SURE A+
✔✔orthologs - ✔✔speciation, homologs within different species that have the same
function
✔✔Blosum 62 - ✔✔a positive number indicates that the amino acid has been replaced
by a similar amino acid
✔✔myoglobin - ✔✔found in muscles, is folded into 8 alpha helix, interior nonpolar.
✔✔heme - ✔✔a prosthetic group for globins
✔✔2,3-bisphosphoglycerate - ✔✔(2,3-BPG) a negative allosteric modulator when O2
binds it squeezes out 2,3-BPG and increases the affinity for O2
✔✔Bohr Effect - ✔✔when CO2 and H+ bind to Hb they lower the pH causing O2 to be
released. This is good because more o2 released at contracting muscles that make a lot
of CO2 and H+
✔✔ adenine - ✔✔purine
✔✔guanine - ✔✔purine
✔✔cytosine - ✔✔pyrimidine
✔✔thymine - ✔✔pyrimidine
✔✔DNA helix - ✔✔right handed
✔✔pKa - ✔✔susceptibility of a proton removal by a reaction with a base
, ✔✔pH=Pka - ✔✔deprotonation is halfway doen
✔✔Henderson-Hasselbach equation - ✔✔pH=pKa+log[A-]/[HA]
✔✔glycine - ✔✔Hydrophobic amino acid, G, Gly
✔✔alanine - ✔✔Ala, A, hydrophobic AA
✔✔proline - ✔✔pro,p, hydrophobic aa
✔✔valine - ✔✔val, v, hydrophobic aa
✔✔leucine - ✔✔leu, l, hydrophobic aa
✔✔isoleucine - ✔✔ile, i, hydrophobic aa
✔✔methionine, - ✔✔met, m, hydrophobic aa
✔✔tryptophan - ✔✔trp, w, hydrophobic aa
✔✔phenylalanine - ✔✔phe, F, hydrophobic aa
✔✔lysine - ✔✔lys, K, positive aa
✔✔arginine - ✔✔arg, R, positive aa
✔✔histidine - ✔✔his, H, positive aa
✔✔serine - ✔✔ser, S, polar aa
✔✔threonine - ✔✔thr, T, polar aa
✔✔tyrosine - ✔✔tyr, y, hydrophobic a.a. aa
✔✔asparagine - ✔✔asn, N, polar aa
✔✔glutamine - ✔✔gln, Q, polar aa
✔✔cysteine - ✔✔cys,C, polar aa
