- The amino acid sequence (primary structure) and 3D shape (tertiary structure) of the rhodopsin has been determined and the various protein domains have also been identified with precision (see figures below). The red arrow indicates the amino acid lysin (K) that binds to the oxygen of the retinol (indicated by the blue arrow). The purple arrow indicates the retinal bound to the rhodopsin. In healthy individuals, retinal is abundant and can binds to the rhodopsin, making it functional (light-sensitive).

- A one-to-one protein (P)-ligand (L) complexation (P + L PL) has a dissociation equilibrium constant (Kd) value of 100 nM at 25°C, and the Kd remains the same at 37°C. 1) What is AS of binding at 25°C? Assume ACp of the binding is 0 over the temperature range. AS = 1.34E2 kJ/(mol*K) (note the unit!!) (sig. fig =3) 2) What is the concentration of the PL complex formed at equilibrium when you mix 0.20 uM (microM) of Protein and 1.0 uM of Ligand together at 37°C? PL at equilibrium = 8.1E-1 uM (note the unit!!) (sig. fig =2)arrow_forwardWould you say that the GadC anti porter exhibits the same pH dependence as the AdiC anti porter?

- 5. Anesthetic gases used in surgery are known to bind to the hemoglobin molecule in red blood cells. The diagram below illustrates O2 binding curves of normal human HbA in the presence of the anesthetic gas dichloromethane (DCM).

State whether the following descriptions of the lab experiment are valid or not, and explain why you say Yes or No: a.The experiment would be significantly more accurate if absorbance readings were recorded for a range of wavelengths, not just for 595 nm.b.The experiment has limited accuracy because it does not account for the absorbance of light by the other components (components that are not the dye-protein complex, such as excess dye that is not bound to any protein) of the solution.c.The absorbance reading measures practically all the protein content in the solutionsarrow_forward5. n° of 2-chloro-2-methylpropane is 1.3850. If a 1g sample of 2-chloro-2-methylpropane was contaminated with 1 drop of ethanol, what do you think the effect would be on the refractive index and by approximately how much? (1 drop of ethanol weighs about 0.03 g).arrow_forward
