What else can I help you with?
Is there another name for carrier proteins?
Yes, carrier proteins are also known as carrier molecules or transport proteins. They facilitate the movement of molecules across cell membranes by binding to specific substances and transporting them across the cell.
What type of proteins are used in facilitated diffusion?
Facilitated diffusion involves the use of integral membrane proteins known as carrier proteins or channel proteins to help transport specific molecules across the cell membrane. These proteins provide a pathway for the molecules to cross the lipid bilayer more efficiently than simple diffusion.
What is the difference between channel and carrier proteins in terms of their mechanisms of transporting molecules across cell membranes?
Channel proteins facilitate the passive movement of molecules across cell membranes by creating a pore or channel for them to pass through. Carrier proteins, on the other hand, actively transport molecules by binding to them and undergoing a conformational change to move them across the membrane.
Does Exocytosis use a channel or carrier protein?
Exocytosis uses carrier proteins to transport molecules out of the cell. These carrier proteins facilitate the fusion of transport vesicles with the cell membrane, enabling the release of molecules outside the cell.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What are comparison and contrast of the structure and function of channel proteins and carrier proteins?
channel proteins transport large molecules through the interior cell carrier proteins wait until energey is provided and move molecules out and inside the cell
What are Channel and carrier proteins?
Channel proteins are on the plasma membrane, selectively transport the solutes such as ions, small and large proteins across the membrane. Carrier proteins also membrane proteins that allow diffusion of different molecules. Both proteins are chemically made up of amino acids.

What is used in facilitated diffusion to assist the transport of sugar and sodium?
transport proteins both are carrier proteins and channel proteins
What is the facilitated diffusion to assist the transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What are the four types of protein in a cell membrane?
The four main types of proteins found in a cell membrane are integral proteins, peripheral proteins, glycoproteins, and channel proteins. Integral proteins are embedded within the lipid bilayer, while peripheral proteins are attached to the surface of the membrane. Glycoproteins have carbohydrate chains attached to them, and channel proteins help facilitate the movement of specific substances across the membrane.
Are carrier proteins are located in the membrane?
yes they are
What do myelin sheath membranes lack which makes them good insulators?
Channel and carrier proteins
Why can channel proteins mediate much more rapid transport than carrier proteins?
Channel proteins allow ions or molecules to flow freely through a pore, leading to rapid transport without requiring conformational changes. Carrier proteins, in contrast, undergo conformational changes to transport substrates individually, making the process slower than channel proteins.
Which of the following types of membrane proteins are responsible for facilitated diffusion?
Channel proteins and carrier proteins are responsible for facilitated diffusion. Channel proteins form hydrophilic channels that allow specific ions or molecules to pass through the membrane, while carrier proteins undergo conformational changes to transport molecules across the membrane.
