Best Answer

Cholesterol is found in every cell of your body. It is especially abundant in the membranes of these cells, where it helps maintain the integrity of these membranes, and plays a role in facilitating cell signaling-- meaning the ability of your cells to communicate with each other so you function as a human, rather than a pile of cells.

Why is cholesterol so important to the plasma membrane?

why are cholesterol molecules important components of cell membranes


Is a plasma membrane composed of Cholesterol molecules?

Yes - cholesterol is found in cell membranes. Cholesterol helps to stabilise the membrane. It is also sometimes involved in cell signalling.


Does plasma membranes have molecules on their surface that identifies them?

No


What major types of lipid are found in the plasma membranes?

Phospholipids, cholesterol, & glycolipids.


What causes these molecules in the plasma membrane of the cell lend stability to the membrane and prevent it from becoming less fluid at low tempatures?

Cholesterol molecules and protein molecules help stabilize the cell membranes. Cholesterol prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. Cholesterol is only found in animal cells.


What is the Main structural component of a plasma membrane?

The basic structure of all membranes is the same. They are composed of two layers of phospholipid molecules, associated with other molecules including proteins, carbohydrates and cholesterol. I hope this helps.


Which molecule in animal plasma membranes stiffens and strengthens the membrane?

Methionine, a sulfur-containing amino acid, is an intermediary that helps strengthen cell membranes. The infamous cholesterol that we're often advised to avoid also helps maintain the integrity of cell membranes (and to a lesser degree, the integrity of the membranes of organelles inside the cell). The cell's plasma membrane is considered a fluid mosaic where the lipid molecules in the bilayer move about in the membrane. However, cell membranes may experience transitions which make their molecules more gel-like or nearly solid.


What are the two principal types of molecules in plasma membranes?

phospholipids and proteins.


These are primary molecules making up plasma membranes in cells?

lipids
