- REFLECT AND APPLY You are purifying a protein for the first time. You have solubilized it with homogenization in a blender followed by differential centrifugation. You wish to try ammonium sulfate precipitation as the next step. Knowing nothing beforehand about the amount of ammonium sulfate to add, design an experiment to find the proper concentration (% saturation) of ammonium sulfate to use.arrow_forwardREFLECT AND APPLY Why is it better, when running a marathon, to drink a beverage with sugar for energy rather than one with amino acids?arrow_forwardREFLECT AND APPLY A biochemistry student characterizes the process of cooking meat as an exercise in denaturing proteins.

To be absorbed into the bloodstream, it must pass through the membrane lining the stomach and the small intestine. Electrically neutral molecules can pass through a membrane more easily than can charged molecules. Would you expect more aspirin to be absorbed in the stomach, where the pH of gastric juice is about 1, or in the small intestine, where the pH is about 6? Explain your answer.arrow_forward
