Unformatted text preview: assive transport (uses Diffusion) – Active transport (uses Energy) – Bulk transport (endo- and exocytosis) What is diffusion? What makes it happen? Does it requires external energy? What is the goal of this process? This membrane is selectively permeable.
Solute particles cannot permeate the membrane. Water can. What moves? What drives the movement? What is the goal? Do we need energy? How can diffusion be used to explain this? What is the water doing? Membrane Structure & Function
• Fluid mosaics of lipids and proteins • Selectively permeable • Transport mechanism
