What is the phYSICAL parts of cell membrain?

Answer 1

The cell membrane is composed of a phospholipid bilayer and proteins, which are embedded in the bilayer.

Answer 2

The physical parts of a cell membrane include phospholipid molecules that form a lipid bilayer, proteins embedded within the lipid bilayer, cholesterol molecules that help regulate membrane fluidity, and carbohydrates attached to proteins and lipids on the outer surface. Together, these components make up the structure of the cell membrane, providing a selectively permeable barrier that separates the cell from its external environment.
