What are carrier proteins?
Carrier proteins are proteins that bind to specific molecules and transport them across cell membranes. They are essential for facilitating the movement of molecules like ions, nutrients, and signaling molecules in and out of cells. Carrier proteins exhibit selectivity and saturation kinetics in their binding and transport activities.
Carrier proteins do not require energy to transport amino acids into a cell?
Carrier proteins facilitate the movement of amino acids across the cell membrane through facilitated diffusion, which does not require energy input. This process relies on the concentration gradient of amino acids across the membrane.
Proteins that attach molecules in order to deliver them to another site?
These proteins are likely transport proteins, such as carrier proteins or channel proteins, which bind to specific molecules and facilitate their movement across cell membranes or through the bloodstream. These proteins help to transport essential molecules like hormones, ions, and nutrients to their target destinations in the body.
What are the four types of proteins found in the cell membrane?
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!
What are the proteins used in active transport called?
Proteins used in active transport are called transport proteins. These proteins are responsible for moving molecules or ions across a cell membrane against their concentration gradient, requiring energy in the form of ATP.
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.

Carrier proteins transport glucose into a muscle cell.?
carrier proteins transport glucose into a muscle cell
Why would model B be better for moving nutrients in and out of the cell?
Model B may be better for moving nutrients in and out of the cell because it incorporates carrier proteins that can facilitate specific transport of nutrients across the membrane. These carrier proteins can selectively bind to certain nutrients and transport them across the membrane more efficiently than simple diffusion.
Carrier proteins do not require energy to transport amino acids into a cell?
Carrier proteins facilitate the movement of amino acids across the cell membrane through facilitated diffusion, which does not require energy input. This process relies on the concentration gradient of amino acids across the membrane.
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.
Are carrier proteins in the cell membrane?
yes they are

These proteins help to transport essential molecules like hormones, ions, and nutrients to their target destinations in the body.
Is carrier proteins active or a passive transport?
Carrier proteins are involved in facilitated diffusion, a type of passive transport. They bind to specific molecules and assist in their movement across the cell membrane down their concentration gradient without requiring energy input from the cell.
How do nutrients get into cells and what is the process involved in their transportation?
Nutrients enter cells through a process called active transport or passive diffusion. Active transport requires energy and specific carrier proteins to move nutrients across the cell membrane, while passive diffusion relies on the concentration gradient to allow nutrients to move freely into the cell. Once inside the cell, nutrients are transported to different parts of the cell through various pathways, such as vesicle transport or protein channels.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What carrier proteins help in facilitated diffusion in the cell membrane?
Integral proteins.
