Active Transport, Decoded

Why would a cell spend energy to move something? Because sometimes it has to go uphill. In 3 minutes: passive vs active transport, ATP, the sodium-potassium pump (3 Na+ out, 2 K+ in), why the pump matters, bulk transport, endocytosis (phagocytosis and pinocytosis), exocytosis, and a quick check question.
