In the model, this is the grape. Cell membrane close cell membraneThis surrounds the outside of animal cells and controls what can enter and exit it.: In the model, this is the balloon.

Like a mosaic, the cell membrane is a complex structure made up of many different parts, such as proteins, phospholipids, and cholesterol. The relative amounts of these components vary from ...

At physiological temperatures, cell membranes are fluid; at cooler temperatures, they become gel-like. Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic ...

"But having both a bilayer-forming lipid, which provides the basic structure for the cell membrane, and a non-bilayer-forming lipid, such as cholesterol, which adds stability, seems to be a ...
