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 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
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 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 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.
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 are the three types of transport proteins?

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.
Where are the carrier proteins and channel proteins found?
Carrier proteins are typically found embedded in the cell membrane, where they facilitate the passage of specific molecules across the membrane through binding and conformational changes. Channel proteins are also found in the cell membrane and form pores that allow for the passive movement of molecules down their concentration gradient.
What is a non example for carrier protein?
A non-example of a carrier protein is a channel protein, which facilitates the passive transport of ions and molecules across the cell membrane without binding to them. Unlike carrier proteins, which undergo conformational changes to move specific substances, channel proteins provide a pore that allows substances to flow through without direct interaction. Examples of channel proteins include ion channels and aquaporins, which specifically transport ions and water, respectively.
