BIOL 0280 Midterm: Exam1 2006 blank
Document Summary
1: [4] given that pk1 = 2; pk2 = 10; pkr = 4, draw the ionization states and calculate the pi of aspartate. Write the pi on the line below pi : [4] draw the structures of the amino acids phenylalanine and glutamate in the ionization state you would expect at ph 7. 0. Why is glutamate very soluble in water, whereas phenylalanine is much less soluble: [3] a. 2: [4] draw the dipeptide ala-val at ph 7 (be certain to draw all hydrogens). Indicate on your drawing (above) the bond that has limited rotation. Circle the correct answer: [2] for enzymes in which the slowest (rate-limiting) step is the reaction. K m becomes equivalent to: cat: k, the [s] where v. 0 = v max: the dissociation constant, k d, for the es complex, the maximal velocity, the turnover number.
