What else can I help you with?
What does a channel protein do in the context of cellular transport?
A channel protein helps facilitate the passage of specific molecules or ions across a cell membrane, allowing for efficient and selective transport in and out of the cell.
Is aquaporin a channel protein?
Yes, aquaporin is a type of channel protein that facilitates the transport of water molecules across cell membranes.
What is the function of a channel protein in cellular transport?
A channel protein in cellular transport acts as a passageway for specific molecules to move in and out of the cell, helping to regulate the flow of substances across the cell membrane.
What is the purpose of a channel protein in cellular transport?
A channel protein in cellular transport acts as a passageway for specific molecules to move in and out of the cell, helping to regulate the flow of substances and maintain the cell's internal environment.
Is a protein that forms an ion channel through a membrane is most likely to be a peripheral protein a trans membrane protein a phospholipid an enzyme or an entirely outside the phospholipid?
A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.
What type of transport protein is a sodium potassium pump?
It is a carrier protein
Difference between ion pump and channel?
An ion pump actively transports ions across the cell membrane against their concentration gradient using ATP energy, while an ion channel is a passive protein that allows ions to move down their concentration gradient in or out of the cell membrane. Ion pumps are selective in the ions they transport, while ion channels are typically nonspecific or selective for specific ions.
What is a large protein in the cell membrane that transports a specific ion?
Ion channel
Is an ion channel a passive transport?
they are type of passive transports
Is a protein channel active transport?
They are two major active transport proteins.
Changes in permeability?
Receptor protein is coupled with an ion channel
What occurs when a receptor protein is coupled with an ion channel?
Changes in permeability occur when a receptor protein is coupled with an ion channelchanges in permeability
What are the cell surface receptorss?
G-protein, ion-channel and enzyme-linked protein receptors.
What does a channel protein do in the context of cellular transport?
A channel protein helps facilitate the passage of specific molecules or ions across a cell membrane, allowing for efficient and selective transport in and out of the cell.
Is aquaporin a channel protein?
Yes, aquaporin is a type of channel protein that facilitates the transport of water molecules across cell membranes.
A specific protein that recognizes certain molecules bringing them across the membrane?
The protein you are referring to is likely a transporter protein, which is responsible for facilitating the transport of specific molecules across the cell membrane. These transporter proteins bind to their target molecules on one side of the membrane and undergo a conformational change to transport the molecules to the other side. Examples include glucose transporters and ion channels.
What is the function of a channel protein in cellular transport?
A channel protein in cellular transport acts as a passageway for specific molecules to move in and out of the cell, helping to regulate the flow of substances across the cell membrane.
