What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

• Diffusion
• Osmosis
• Active Transport
• Facilitated Diffusion

Osmosis is the movement of _____ across a membrane.

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

Active transport requires _____ to move materials across the cell membrane.

• energy

When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell. 

• active transport
• concentration
• diffusion
• equilibrium

Cells use energy to move materials across a membrane (low to high concentration).

• Active transport
• Passive transport
• Diffusion
• Osmosis

Particles are removed from a cell (pushed out).

• In high concentration

Cell membrane surrounds a particle and encloses it (for large particles)

• Endocytosis
• Exocytosis
• Permeable
