What else can I help you with?
A protein on the cell membrane that recognizes and binds to specific substances is called a?
Enzyme
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
Molecules that permeate a plasma membrane by facilitated diffusion is what?
Molecules that permeate a plasma membrane by facilitated diffusion are typically larger, polar molecules that cannot pass through the lipid bilayer unassisted. These molecules rely on specific transport proteins embedded within the membrane to facilitate their movement across the membrane down their concentration gradient.
What molecules located in the membrane assist with facilitated diffusion?
Protein channels and carrier proteins are molecules located in the membrane that assist with facilitated diffusion. These proteins help facilitate the movement of specific molecules such as ions, sugars, and amino acids across the cell membrane.
What binds to receptor molecules on the host cell membrane?
Ligands bind to receptor molecules on the host cell membrane. These ligands can be hormones, neurotransmitters, or other signaling molecules that trigger a cellular response when they bind to their specific receptors.
What is a specific protein that recognizes certain molecules?
balls
A protein on the cell membrane that recognizes and binds to specific substances is called a?
Enzyme
A specific protein that recognizes certain molecules?
There are antibodies and cell-surface receptors and enzymes; is there a more specific A. in view?
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.
Can polar molecules pass through the cell membrane?
Yes, polar molecules can pass through the cell membrane with the help of specific transport proteins.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a 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.
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.
How do polar molecules cross the cell membrane?
Polar molecules cross the cell membrane through a process called facilitated diffusion, where they move with the help of specific transport proteins embedded in the membrane. These proteins create channels or carriers that allow polar molecules to pass through the hydrophobic interior of the membrane.
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
How do large polar molecules pass through the membrane?
Large polar molecules pass through the membrane by using specific transport proteins that facilitate their movement across the lipid bilayer.
