Question
15. The production of ADP and in reaction. NAME organic phosphate ion from ATP is representative of a (m) B) condensation C) D) transfer hydrolysis E) endothermic 16. Which of the following statements about aromatic amino acids is correct? A) Tryptophan and more B) depending ring structure results in its being categorized as aromatic or basic, on pH a molar The major contribution to the characteristic absorption of light at 280 nm by proteins ultraviolet than tryptophan. is D) E) presence of a ring structure in its R group determines whether or not am amino is aromatic. 17 Titration of valine (diprotic acid) by a strong base, for example NaoH, reveals two pK's The titration reaction occurring at pKi (pK 2.30) is A) -COOH OH B) -COOH -COO H2O NH2 -COO -NH C) -COO -NH2 -COOH -NH2. D) NH3 OH NH2 H2O. E) NH2 OH NH H20 18 Which of the following is not a triprotic amino acid? A) Glycine B) Arginine C) Histidine D) Lysine E) Glutamic acid 19 In the titration curve of glycine, pKi 2.34 and pK2 9.60. What is the pl value, net average charge at pH 2.34, and pH 9.60? A) 6.00, -0.5, 0.5 B) 6.97, -0.25, 0.25 C) 5.97, -0.5, 0.5 D) 5.97, 0.5, -0.5 E) 5.97, 0.25, -0.25Explanation / Answer
15) the generation of ADP and inorganic ion from ATP is exergonic reaction and not endegonic as it releases energy in during conversion.
The reaction is Hydrolysis of ATP by reaction with water.
16) Tyrosine and tryptophan both have some hydrophilic character (containing oxygen or nitrogen in the sidechain), while phenyl-alanine is completely non-polar (so false)
b) ring strucutre remains same irrespective of pH
c) False tryptophan is responsible for most of the absorbance of ultraviolet light (ca. 280 nm) by proteins.
d) Correct
e) correct: benzene ring determines the aromtic character
17) The dicarboxylic acid reacts at first step with ammonia and equilibrium constant is K1.
