What is the term for the movement of water molecules through a selectively permeable membrane from an area of high concentration to an area of low concentration?
Osmosis
What is the term for the ability of a solution to exert osmotic pressure?
Osmolarity
What is the type of protein that facilitates the transport of water molecules across the cell membrane?
Aquaporin
Which type of transport involves the movement of molecules from an area of high concentration to an area of low concentration without the use of energy?
Passive transport
What is the term for the movement of molecules from an area of high concentration to an area of low concentration with the assistance of transport proteins?
Facilitated diffusion
What is the term for the ability of a solution to maintain a stable osmotic pressure?
Tonicity
What is the primary function of the cell membrane in terms of transport?
Maintaining homeostasis through transport
Learn about the different mechanisms of membrane transport, including facilitated diffusion and osmosis. Understand how molecules pass through protein channels and transporters, and how these processes differ from simple diffusion.
