QUESTION 36 According to the diagram, which pH is the one at which this amino acid will have a net charge of O? Titration of an amino acid 12 10 8 PH 6 5 4 5 2 0 2 1.5 0.5 0 1 OH-(equivalents) A. 6 B. 1.5 O c.0.5 D. 11 E 1 QUESTION 37 The benefit of measuring the initial rate of a reaction Vo is that, at the beginning of a reaction: O A. Vo = Vmax: OB. changes in km are negligible, so Km can be treated as a constant. O C. [ES] can be measured accurately. O D. changes in () are negligible, so (S) can be treated as a constant. E. varying (S) has no effect on Vo
