What biomolecule helps transport molecules across the membrane?
proteins
What helps molecules diffuse across membrane through transport proteins?
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.
What is the purpose of transport for proteins?
Carrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which theytransportsubstances.
Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
What biomolecule helps transport molecules across the membrane?
proteins
How do carriers proteins facilitate passive transport of molecules across a membrane?
Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through the membrane.
What is the membrane that surrounds the cells?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
How do transport proteins make make it easier for certain molecules to diffuse across a membrane?
Facilitated diffusion is the diffusion of molecules.across a membrane through transport proteins. Transport proteins make it easier for molecules to enter or exit acell. But the process is still a form of passive transport.
What are function of membrane proteins?
Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across 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
Why do cells need carriers proteins that transport glucose?
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
If there's a transfer protein then its NOT diffusion ... its active transport.
What is a holes in plasma membrane through which molecules pass across capillary wall?
The plasma membrane is made up of a lipid bilayer and some proteins. The transmembrane proteins are the structures which are involved in the transport of molecules in or through the cell.
