What are the protein molecules in a cell membrane that assist in cell transport?
Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.
Is water a passive diffusion or facilitated diffusion or active trensport or phagocytosis?
Passive diffusion. Water moves from an area of high concentration to an area of low concentration. It is not facilitated diffusion, as it does not require transport proteins to assist it's movement. It is not active transport because it is not moving to an area of higher concentration, and it does not require enzymes or energy to move. Phagocytosis is also incorrect because it is when large particles are "enveloped" by the cell membrane of a larger cell and taken into the larger cell.
The cell uses energy to transport glucose through the cell membrane?
Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
How does a cell membrane allow nutrients to get in?
The cell membrane is semi-permeable, which means that it allows certain substances to go through.For substances that are too large, there are vacuoles and transport proteins that assist the large substances.There is also facilitated transport, passive transport, and active transport. Passive transport is the only one where substances can go through the membrane without the cell expending energy.
How does a cell transport nutrients and wastes across the cell membrane?
A cell can transport materials in many different ways. The simplest isdiffusion; where molecules simply move from areas of higher to lower concentration through the cell membrane. If they are incapable of doing so (because of size or charge) , carrier proteins assist molecules, called facilitated diffusion. Ions (charged molecules) can go through passages called ion channels. Endocytosis happens when cells take in large molecules by the cell membrane surrounding the molecule and pinching off to form a vesicle. Finally, exocytosis is basically the opposite of endocytosis; the cell gets rid of large molecules by vesicles fusing with the cell membrane and releasing their contents outside the cell.

In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion

How are diffusion and facilitated diffusion diffrent?
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.
What molecules located in the membrane assist with facilitated diffusion?
Usually proteins are the molecules doing the selection of what other molecules get into or out of a cell.

Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
Does facilitated diffusion need membrain protein?
The proteins may assist in the movement of substances by facilitated diffusion or active transport. These mechanisms of movement are known as carrier mediated transport.Each carrier protein is designed to recognize only one substance or one group of very similar substances. Research has correlated defects in specific carrier proteins with specific diseases.
What is the role of transport proteins within the plasma membrane?
The membranes around cells and even around some organelles do not allow much to go in and out. If the substance is too large, it can't move in without help. If the charge is 'incorrect', it needs help as well.
What is facilitated mean?
"help" / "assist"
What is facilitator?
Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.
