Transport Across Cell Membranes

016 - Transport Across Cell Membranes Paul Andersen describes how cells move materials across the cell membrane. All movement can be classified as passive or active. Passive transport, like diffusion, requires no energy as particles move along their gradient. Active transport requires additional energy as particles move against their gradient. Specific examples, like GLUT and the Na/K pump are included. Do you speak another language? Help me translate my videos: http://www.bozemanscience.com/transla...
