Based on what we learned about plasma membrane, can you explain the following hypothetical scenario? 1. You are observing a plasma membrane of a certain cell. You notice that there are two groups of ions in the interstitial fluid and cytosol; Na + and Cl -. You observe that Na +(ions) are being transported from IF to cytosol faster that Cl -(ion), though both of these are ions and they have similar quantities. Why is that? 2. You also observe that IF contains faty acid molecules, which are beng ransported from IF to cytosol even faster than Na + . What is the reason for this?.
