The molecule shown to the right is the result of a(n) acting on the amino acid oxidoreductase. leucine lyase, leucine hydrolase, leucine oxidoreductase. lysine lyase, lysine An ionic bond between two nonmetals could have which of the following electronegativity differences? 0.25 1.35. 1.85 2.15 5.25 Which of the following cholesterol-carrying proteins is most abundant in the blood? HDL VLDL LDL DHLDL Chylomicrons Nicotine, shown to the right, contains how many hydrogen atoms? Nicotine, shown to the right, contains how many chiral centers? Nicotine, shown to the right, contains how many atoms with trigonal pyramidal molecular geometry? 0 1 6 12 14 Which of the following esters, upon hydrolysis, produces a three-carbon alcohol as one of the products? propyl pentanoate decyl propanoate ethyl 3-hydroxyoctanoate pentyl decanoate The secondary structure of a protein is held together by the number of polypeptide chains. peptide bonds. the overall fold of a polypeptide chain. the number of alpha helices and beta sheets. hydrogen bonding between amino acids. is synthesized from glucose. Vitamin A Lipoic acid Vitamin C Cholesterol Vitamin E A bond angle of approximate 120 degree occurs somewhere in which of the following molecules? ethyne I -bromopropene cyclopropane cyclobutane a molecule with tetrahedral geometry Of the ten reactions of glycolysis, how many are lyase reactions? 0 1 2 3 4Explanation / Answer
51. the secondary structure gives information about hydrogen bond donar and acceptor residues so the secondary structure of protein is held together is held by alpha helics and beta sheets , so option D is correct
52. Vitamin C also called ascorbic acid can be synthesised from glucose. it is also synthesised from
galactose . so the Option C is coorect
54 option D is correct since in first step 1 ATP IS REQUIRED 2nd step not needed and third step one more ATP is needed if u carry on like that 4 Atps are finally required
53. cyclo propane bond angle is 600 cyclo butane is 900 ethyne is 1800
so 1-bromo propene has nearly 1200 bond angle and option B is correct
50 option A is correct since hydrolysis of ester gives an acid and alchol . propyl achol and pentanoic acid is formed and the alchol is 3 membered
