How do carrier protiens transport substances across cell membrane?
Carrier proteins facilitate the transport of substances across the cell membrane by binding to the specific molecules they transport and undergoing conformational changes to move the molecules across the membrane. This process is often referred to as facilitated diffusion. It allows for the transport of specific molecules, such as glucose or ions, across the membrane, down their concentration gradient.
A special molecule that uses energy to push molecules through a membrane of a cell is called?
The special molecule is called ATP, which stands for adenosine triphosphate. ATP provides the necessary energy to power transport proteins in the cell membrane to move molecules across it.
The diagram represents movement of a large molecule across a membrane?
It depends on what is moving across the membrane. Some molecules use transport proteins and the cell would need those embedded in the membrane. Water doesn't need them and it freely moves in and out.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
How does a cell move a molecule that is too large transport proteins?
Cells may use mechanisms such as endocytosis to engulf and transport large molecules with the help of specialized transport proteins. These transport proteins facilitate the movement of large molecules across the cell membrane by forming vesicles that enclose the molecules and transport them to their destination within the cell. Once inside the cell, the vesicle can fuse with other cellular compartments to release the molecule for further processing or use.
How do carrier proteins facilitate the passive transport of molecules across a 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.
What type of molecule can be used as a tunnel to move compounds across the cell membrane?
Carrier proteins are a type of molecule that can be used as a tunnel to move compounds across the cell membrane. These proteins bind to specific molecules and undergo conformational changes to transport them across the membrane. This process is known as facilitated diffusion.
Does facilitated transport require energy for the movement of molecules across the cell membrane?
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
What biomolecule helps transport molecules across the membrane?
proteins
What is it called when transport proteins to help large molecules like glucose across the cell membrane?
Facilitated diffusion is the process by which transport proteins help large molecules like glucose cross the cell membrane. These proteins create a channel or carrier mechanism that allows the molecule to move across the membrane along its concentration gradient.
