What is the main difference between passive and active transport?

Back

Passive Transport does NOT require energy, while Active Transport DOES require energy.

Front

Equilibrium refers to when the concentration of molecules on one side of the membrane are _________ to the other side of the membrane.

Back

Equal

Front

Diffusion is the movement of molecules ...

Back

down a concentration gradient (from a high concentration to a low concentration)

Front

What is the main difference between diffusion and facilitated diffusion?

Back

Facilitated diffusion requires the help of a protein to transport molecules, whereas in diffusion the molecules transport directly across the membrane.

Front

What is the movement of water down a concentration gradient (from high to low concentration)? Options: Diffusion, Osmosis, Facilitated Diffusion, Active Transport.

Back

Osmosis

Front

Going DOWN a concentration gradient refers to ...

Back

Not using energy to transport from a high to low concentration.

Front

Hypotonic solution

Back

A solution that contains LESS solutes than the cell, causing the water to rush IN of the cell.
