Passive Transport. No energy is used [High] [Low] (it’s the natural flow) This means it goes down a concentration gradient. What are the three types of passive transport?. 1. Diffusion 2. Osmosis 3. Facilitated Diffusion. [High] [Low]. Diffusion. Osmosis. CH 2 OH. OH. +. - PowerPoint PPT Presentation

Protein PumpsProtein Pumps: proteins use energy to pull or pump
materials into or out of the cell to stockpile or store substances the cell needs

• When a particle is engulfed into the cell.• 2 types
1. Phagocytosis: When a cell wraps part of its membrane arounda large particle forming a “pocket” or vesicle
2. Pinocytosis: The same process, but with smaller particles or liquids
Endocytosis
