Given the vo vs. S plots below for an enzyme in the presence or absence of a competitive inhibitor, Enter True or False for each of the following statements. CompetitiveInhibition.png Prompt Response The K M a p p of the inhibited enzyme is larger than the KM of the uninhibited enzyme because the KM of the inhibited enzyme has changed. Addition of more inhibitor will not change the K M a p p of the inhibited enzyme. The vo at saturating substrate concentration will be the same for the inhibited and uninhibited reaction. Using one-half the concentration of inhibitor will increase the vo at saturating substrate concentration.

The hemoglobin variant Hb Nancy contains a substitution where the beta chain Tyr-β145 is substituted with an aspartate. The result is disruption of the position of the C-terminal His-β146 so that it cannot form salt bridges with Lys-α40 and Asp-β94 such that the T state cannot be stabilized even in the absence of oxygen. The oxygen saturation curve for Hb Nancy is shown below compared to normal Hb A at pH 7.2 and pH 7.4. Use the graph to determine the Hb that best is associated with each property. AxSA4.png Prompt Response Greater Bohr effect Greater cooperativity with respect to O2 binding Greater affinity for O2 More R state at low pO2

The imidazole side chain of the hemoglobin beta chain residue His-β146 has a pKa of 7.9 when in the T state (shown below). Determine how its ionization state will change and how it will affect its interaction with the Asp-β94 side chain as the pH shifts from 7.2 in the muscle to 7.4 in the lungs. Enter Increase, Not change, or Decrease. 1b86.png Prompt Response His-β146 imidazole ionization state will His-β146 imidazole interaction with Asp-β94 side chain will

Two of the corners of open rectangular box ABCDEFGH are B = (15, 3, 7) and H = (10, 9, 12). You are tasked with programming a drone to move from B to the midpoint of AD in 2 minutes, and then from there to G in 3 minutes. Provide two sets of parametric equations (one for the first part and one for the second part) that would accomplish this, using t = 0 to represent when the drone is at B. Note: Your equations should give the equations of G when t = 5. Click ‘True’ when finished
