4 Mechanisms of transport across membranes
Diffusion
Osmosis
Active Transport
Bulk Transport
which of those are active/passive
osmosis and diffusion are passive
active transport and bulk transport are active
Types of Diffusion
simple diffusion
facilitated diffusion (requires a membrane protein)
Types of Osmosis
simple diffusion
facilitated diffusion with a specific membrane protein called aquaporin
Types of active transport
Primary Active transport (energy in ATP)
Secondary Active transport (energy in conc gradient)
Types of Bulk transport
endocytosis
exocytosis
