- More ratios. Through the use of nuclear magnetic resonance spectroscopy, it is possible to determine the ratio between the protonated and deprotonated forms of buffers. (a) Suppose the ratio of [ A- ]A I to [HA] is determined to be 0.1 for a buffer with pKar6.0.pKa = 6.0. What is the pH? (b) For a different buffer, 91974 suppose the ratio of [ A- ]lA J to [HA] is determined to be 0.1 and the pHpH is 7.0. In this case, what is the pKapKa of the buffer? (c) For another buffer with pKa=7.5PKa = 7.5 at pH 8.0pH 8.0, what is the expected ratio of [ A- ][A ] to [HA]? doarrow_forwardRespiratory paralysis.

- Enzymes catalyze chemical reactions. What constitutes the active site of an enzyme? What are the turnover number (kcat), the Michaelis constant (Km), and the maximal velocity (Vmax) of an enzyme? The kcat (catalytic rate constant) for carbonic anhydrase is 5 × 105 molecules per second. This is a “rate constant,” but not a “rate.” What is the difference? By what oncentration would you multiply this rate constant in order to determine an actual rate of prod- uct formation (V)? Under what circumstances would this rate become equal to the maximal velocity (Vmax) of the enzyme?arrow_forwardThank you for helping me. I have to questions. In solution B, if we choose two other points on the graph for calculating the slope, wouldnt the values for Km/Vmax be different than 6.1? Why did you choose exactly those points on the graph?

K+ Na+ Mg2+ not enough informationarrow_forwardHandwrite everything in the picture The first law of thermodynamics, AU= q - w (2) where AU = internal energy change for system q = energy transfer into system by heat flow -W = work done by system may be applied to the actual Calorimeter process, which is assumed to be adiabatic (q = 0). In the present experiment, w, which consists mainly of the work of stirring, can be neglected' and Eq. (2) then becomes AUc = 0 (3) Since the energy Change is independent of path, one has AU = AU + J Co CdT (4) Since the temperature change is small, it is usually valid to consider C to be constant, so that the integral becomes equal to C(T2 - T1). One then obtains AUT1= -C(T2 - T1) (5) It may be observed that a temperature rise corresponds to a negative AUT1, that is, to a decrease in energy for the imagined isothermal process. The next step is to calculate AU,° from AUT1. Although the energy is not sensitive to changes in pressure, the correction to standard states, called the Washburn correction,…arrow_forward
