What is active transport?

A

Up a concentration gradient: requires energy

21
Q

What is passive transport?

A

Down a concentration gradient: doesn’t not require energy

22
Q

What is osmosis?

A

Diffusion of water down a concentration gradient

23
Q

What is reverse osmosis?

A

Water is forced against it’s concentration gradient

24
