Yooo Sophomores, I'm Here to Hit You with Some Knowledge

Word on the street says that you guys need to be learning about Osmosis, Active Transport, and Diffusion. It some pretty simple stuff, so no need to worry! Diffusion is the movement of a HIGH concentration to a LOW concentration. More specifically there is simple and facilitated diffusion. Simple diffusion is just the movement of a high to low concentration. Facilitated diffusion is diffusion through a protein channel in the membrane.A protein channel is an opening in the membrane that's made out of proteins. Simple and facilitated diffusion do not require energy to move. Active energy does require energy to move. Active transport is movement of molecules moving against the concentrations, so LOW to HIGH concentrations. Osmosis is the diffusion of water. Water will move from a HIGH concentration to a LOW concentration.


HINTS::
1) Simple Diffusion: Simply the definition
2) Facilitated diffusion: facilitated means with help & protein channels help this cross membrane
3) Active Transport: Active requires energy & to be active we need energy.
4) Osmosis: Everyone has seen the movie Osmosis Jones, right?? THINK he was mostly made up of water.


GOOD LUCK!!
