Cell Transport

The movement of molecules across a membrane from high concentration to low concentration is called:

• Osmosis
• Diffusion
• Endocytosis
• Active Transport

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Which is true about active transport?

• It requires energy
• it does not require energy
• It moves substances down the concentration gradient
• it moves material from high to low concentration

Molecules diffusing with the concentration gradient through a protein channel is...

• Facilitated Diffusion
• Simple Diffusion
• Active Transport
• Osmosis

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport

Uses ATP (energy)

• Passive Transport
• Active Transport
