System I: Ion Channels 1. What structures in the cell membrane function as ion channels? Integral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? 1. Charge 2. Size 3. Amount of water the ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an __________nongated______________ channel. 4. Would sodium ions move into

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is‚ we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into or (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

Earth Batteries Dirt makes pretty good batteries. It seems like moist dirt packed tightly works the best. Add just enough water but not too much. I guess if the dirt dries up‚ you’ll have to water the batteries along with the rest of the plants. The soda can version works but I haven’t tested extensively. You don’t really have to use a penny‚ just has to be copper. Perhaps other common materials would work better. Each cell gives you a useless 0.5 volts. But if you link them in series you can
