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.

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.
The cell membrane is made up of phospholipids which are molecules?
The cell membrane is made of a phospholipid bilayer with the hydrophilic ends out and the hydrophobic ends in. There are globular proteins in between the bilayer that assist in transport.
On the outer surface of the plasma membrane there are marker molecules that identify the cell-type Often these molecules are?
These molecules are typically membrane carbohydrates. These assist in the identification of the type of cell.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
Major functions of cell membrane proteins?
Examples of proteins in the cell membrane are pore/channel proteins, carriers, glycoproteins. Therefore protein assist in transport of substances across cell membrane. Cell recognition. Involved in mechanical strength and attachment of the cell membrane ( protein substances surround the cell membrane that allows it to attach to other cells)
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion

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 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.
What is the facilitated diffusion to assist the transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins

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.
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.
What is the importance of chaperone proteins?
Protein molecules that assist in the proper folding that keeps the new polypeptide segregated from "bad influences" in the cytoplasmic environment while it folds spontaneously.
