The drawings below represent binding sites in two different versions of protein M showing only the Adams in relevant amino acid side chains. Consider a positively charged magnesium ion. Pick the binding site you think is most likely to buy magnesium ion and draw the ion in the binding site showing why is binding in that site.

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
