Osmosis
What does osmosis diffuse?
Water
Does it require energy?
No.
What is the end result of diffusion?
Equilibrium
Does it start at high or low concentration?
High concentration
What happens to a cell in pure water?
It swells and may burst.
Are the molecules that use facilitated diffusion larger or smaller molecules?
Larger molecules
How does it get through the cell?
Through the membrane.
Does passive transport require ATP?
No.
What facilitates osmosis?
Aquaporins
What do the molecules pass through?
Proteins
Do molecules move in a pattern?
No
Does passive transport need energy?
No
Does it move towards higher or lower solute concentration?
Towards higher concentration.
How is facilitated diffusion different from regular diffusion?
It uses proteins for help.
What affects the speed of diffusion?
Temperature, concentration difference, and surface area.
What are the main three examples of passive transport?
Simple Diffusion, Facilitated Diffusion, Osmosis
what is an Aquarian?
Its a Protein Chanel that facilitates diffusion of water.
When is this type of passive transport needed?
When a molecule cannot move directly across the cell.
What is the difference between diffusion and osmosis?
Osmosis moves water and diffusion moves particles.
What happens if the molecule loses selectivity with the cell?
It will die.
