the concentration of the solute is lower inside the cell than outside it
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
Transport proteins must be peripheral proteins because they need to be able to move within the cell membrane to facilitate the transport of molecules across the membrane. Peripheral proteins are not embedded within the lipid bilayer of the membrane, allowing them to move more freely and interact with molecules on both sides of the membrane. This mobility is essential for transport proteins to effectively transport molecules across the cell membrane.
The transport of molecules from inside a cell to the outside is called exocytosis. In this process, vesicles containing the molecules fuse with the cell membrane, releasing the contents to the extracellular space.

proteins
Binding: Molecules from the extracellular environment bind to the carrier protein on the cell membrane. Transportation: The carrier protein undergoes a conformational change, allowing the molecules to pass through the membrane. Release: Once inside the cell, the molecules are released from the carrier protein and the protein returns to its original conformation for further transport.

Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
