1. The problem statement, all variables and given/known data According to my book, the Golgi body is the organelle of an animal cell which is responsible for *protein modification* and *sub-cellular localization*. I'm trying to fully grasp what is said above (in a manner that is as easy to understand as possible, without involving anything too complicated). 2. Relevant equations N/A 3. The attempt at a solution About the sub-cellular localization part, does that just refer to the Golgi body making vesicles with proteins in them, where the vesicles go to the locations they're supposed to go to (where the locations are encoded in the proteins) or is there more to the term "sub-cellular localization" than that? I am not a student in health sciences, so please don't assume any knowledge on my behalf! Despite not being a student in health sciences, I want to know the exact truth and not an approximation of it (assuming humankind's understanding is the exact truth). What I mean by this is that, while I don't want to get too technical, I want to be told stuff that are 100% accurate and not (only) stuff that are like 90% accurate just because it would make an explanation easier to understand. Having said that, any input would be GREATLY appreciated (especially since anything I find is way too complex for me to understand)! :) P.S. If what I hypothesized about what the term "sub-cellular localization" means is 100% correct, just telling me that would be good enough for an answer. :) If what I hypothesized is not 100% correct, however, please tell me what is.
