In addition to proteins organic molecules is also found in cellular membranes?
Three different types of molecules appear in the membrane of a cell. These molecules are lipids, proteins, and carbohydrates.
What carries messages out of a cell?
No cell carries messages out of a cell. Hormones are considered to be messengers and as well as some proteins.
What form parts of cell membranes and many of the cell's organelles?
The answer is proteins.
What kind of protein helps some substances cross the cell membrane?
Channel proteins.
Is the cell membrane permitable to everything?
Not everything, no. It depends on the cell, some cell membranes are permeable to water (called osmosis) but not smaller particles like proteins. Whereas, some are permeable to proteins and other small particles but not to larger particles.

What do the proteins in cell membrane do?
Many are active and passive transmember proteins for the passage of material into and out of the cell and some are markers on the cell surface that distinguish one bodies cells from another bodies cells.

Do all chemical substances pass in and out of a cell membrane with equal ease?
no, cell membranes only allow things to pass through it only by using proteins embedded on it for things such as some nutrients and even water. there are two types of these proteins that could be found in the cell membrane, integral proteins, and peripheral proteins. integral proteins are proteins that span throughout the whole cell membrane from one side to another and have polar ends and nonpolar interiors transporting things like nutrients into the cell. peripheral proteins are proteins that only attach to the side of the cell membranes and do not go through it completely. some of these specialized proteins include: aquaporins for transport of water carrier proteins that bind with these necessary molecules to transfer them across the cell membrane glycoproteins that have sugars attached to them channel proteins that allow molecules to freely pass through membrane receptor proteins that bind with proteins on the surface of the cell and enzymatic proteins that help carry out metabolic reactions in the cell
What form parts of cell membranes and many of the cell's organelles?
The answer is proteins.
What might happen to a cell if a required protein was not made in that cell?
The first thing that might happen to a cell if a required protein was not is apoptosis. Apoptosis is programmed cell death. Another outcome might be the loss of some of the function in the protein.
What kind of protein helps some substances cross the cell membrane?
Channel proteins.
Why do cell need transport proteins to functions?
Some molecules are too large to pass through the cell membrane without transport proteins.
Is the cell membrane permitable to everything?
Not everything, no. It depends on the cell, some cell membranes are permeable to water (called osmosis) but not smaller particles like proteins. Whereas, some are permeable to proteins and other small particles but not to larger particles.
What two substances control the movement of the materials into and out of the cell?
Some of the proteins and lipids do control movement of materials into and out of the cell.
What two substances control the movement of materials into and out of cell?
Some of the proteins and lipids do control movement of materials into and out of the cell.
Where do the proteins go after the Golgi?
When proteins are newly formed, they are transported to the cell surface and other parts of the cell in which require protein. These proteins are transported from the cytosol into the biosynthetic-secratory pathway located in the ER.
