Transport Across Membranes Active transport is pumping against the concentration gradient

3 types of Passive Transport ,[object Object]

Diffusion ,[object Object],[object Object]

Passive Transport- Diffusion ,[object Object],[object Object]

Simple Diffusion Across Bilayers

Passive Transort- Osmosis More water Less water

Osmosis: Water down Conc. Gradient

Tonicity More solute in than out
