eukaryotic cells secrete molecules to the outside of the cell as well as incorporate proteins into their plasma membrane by a process called exocytosis. Made by Robert Trager
This video answers the questions: How do these molecules get to the outside of the cell? and What orientation do trans-membrane proteins have after exocytosis?
Great presentation. This little tutorial demonstrates the enormous progression in knowledge of cell biology since my studies in the late '70's. The electronic "blackboard" is also a remarkable inovation (probably commonplace to today's students but pretty nifty for an old bloke like me).
