Unit 2: Midpoint

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not 

Osmosis is the diffusion of

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement
