In this lecture, EKG is going to cover the transport functions of membranes.
We’re going to break down passive transport (diffusion & facilitated diffusion), active transport (primary & secondary), osmosis, and bulk transport (endocytosis & exocytosis).
This is a jam-packed lecture, so make sure you have your study snacks and water bottle ready! Don't get any crumbs on your notes though, and smash that like button!
