What is the movement of particles with the concentration gradient using protein "helpers"?

• diffusion

• facilitated diffusion

• active transport

• enzymatic reactions

During diffusion, when the concentration of molecules on both sides of a membrane is THE SAME, the molecules will

• move across the membrane to outside of the cell

• stop moving across the membrane

• continue to move across the membrane in both directions

• move across the membrane to the inside of the cell

Match the following processes with their descriptions.

• Movement of molecules across a membrane via transport proteins.

• Facilitated diffusion

• Movement of water across a semipermeable membrane.

• Active transport

• Process of taking in materials by engulfing them in a cell membrane.

• Endocytosis

• Movement of molecules against a concentration gradient using energy.

• Osmosis
