the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
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.
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.
Protein pumps are located in the cell membrane and their function is to transport molecules across the cell membrane, regulating the movement of substances in and out of the cell.
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
Proteins in the cell membrane can act as transporters or channels, aiding in the facilitated diffusion of specific molecules across the membrane. These proteins provide a passageway for the molecules to move across the membrane by utilizing their specific structure and function. This process helps regulate the movement of molecules in and out of the cell.

Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
Transport proteins help facilitate the movement of molecules across a membrane by providing a specific channel or carrier for the molecules to pass through. These proteins can be selective, allowing only certain molecules or ions to pass through, and can also be regulated based on the cell's needs. Additionally, transport proteins can function through processes such as facilitated diffusion or active transport to move molecules in or out of the cell.
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
Membrane proteins play crucial roles in cellular function and structure by facilitating the transport of molecules across cell membranes, serving as receptors for signaling molecules, and helping to maintain the integrity and stability of the cell membrane.
