5 Questions
What is facilitated diffusion?
Facilitated diffusion is the process of molecules passing through cell membranes with the help of specific proteins.
What are aquaporins?
Aquaporins are water channel proteins that allow water to pass through cell membranes.
Define osmosis.
Osmosis is the diffusion of water through a selectively permeable membrane.
How do molecules move in osmosis?
Molecules in osmosis move from an area of higher concentration to an area of lower concentration.
What determines the direction of water movement in osmosis?
The concentration of solute molecules, like sugar, determines the direction of water movement in osmosis.
Learn about how water molecules can enter cells through facilitated diffusion, aided by aquaporins. Explore the role of water channel proteins in allowing water to pass through the hydrophobic lipid bilayer of cell membranes.
