Lesson 4: Membrane Transport & Facilitated Diffusion
Duration of Days: 3
Lesson Objective
Describe how electrochemical gradients established by primary active transport systems are utilized by the cell to drive secondary transport or power cellular processes.
What distinguishes a channel protein involved in facilitated diffusion from a protein pump involved in active transport?
How does a cell use active transport to generate chemical or electrical gradients that can be utilized to do cellular work?
2.5- Membrane Transport
2.6- Facilitated Diffusion
2.8- Mechanisms of Transport
Cells use distinct transport mechanisms depending on chemical concentration gradients and energy availability.
