10 Questions
What is the process called when water moves from high to low concentration?
Diffusion
Which type of transport involves large or charged molecules moving through a channel protein in the cell membrane?
Facilitated Diffusion
When does facilitated diffusion occur?
When large or charged molecules move through a channel protein in the cell membrane
What is the term for the movement of any molecule from high to low concentration?
Diffusion
What is the term for the movement of molecules from a high concentration to a low concentration?
Moving down the concentration gradient
Passive transport always requires energy to move molecules from high concentration to low concentration.
False
Diffusion is when any molecule moves from low to high concentration.
False
Osmosis is the movement of water from low to high concentration.
False
Facilitated Diffusion involves the use of energy to move molecules through channel proteins in the cell membrane.
False
Living things do not use the mechanism of passive transport for most substances.
False
Test your knowledge of passive transport with this quiz on diffusion, osmosis, and facilitated diffusion. Learn about how molecules move from high to low concentration without the need for energy, and understand the principles of movement down the concentration gradient.
