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 does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated diffusion does not require energy but relies on carrier proteins to transport molecules across the cell membrane. The carrier proteins assist in the movement of specific molecules down their concentration gradient.
What are the protein molecules in a cell membrane that assist in cell transport?
Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.
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 type of passive transport across a cell membrane that requires special carriers is?
Facilitated diffusion is a type of passive transport that requires special carrier proteins to help molecules move across the cell membrane. These carrier proteins assist in the movement of specific molecules that cannot cross the membrane on their own.
How do carriers proteins facilitate passive transport of molecules across a membrane?
Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through 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.
Do filtration requires a membrane-bound carrier for transport?
No, filtration does not require a membrane-bound carrier for transport. Filtration is a passive process that relies on pressure gradients to separate particles based on size. It does not involve specific carriers to transport molecules.
What ways of moving molecules across a membrane requires energy?
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.
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
Are carrier proteins active or passive transport?
Carrier proteins facilitate active transport by moving molecules or ions across a cell membrane against their concentration gradient. They require energy in the form of ATP to transport substances across the membrane.
Why is energy required for facilitated diffusion?
because those that can't get through the membrane by themselves can get help. transport proteins give them a ride through the membrane. different transport proteins make it easier for certain molecules to get through the membrane without cell using energy
