Final answer:
Phospholipids, cholesterol, and membrane proteins are involved in maintaining the plasma membrane structure.
Step-by-step explanation:
Phospholipids in the plasma membrane play a crucial role in maintaining its structure. These molecules have hydrophilic heads and hydrophobic tails, forming a bilayer that acts as a barrier to control the movement of substances in and out of the cell.
The cholesterol molecules embedded in the plasma membrane are also involved in maintaining its structure. They help regulate the fluidity of the membrane, keeping it stable and resistant to changes in temperature.
The membrane proteins such as integral proteins, peripheral proteins, and glycoproteins are essential for maintaining the plasma membrane structure. Integral proteins transport molecules across the membrane, while peripheral proteins provide structural support and facilitate cellular communication.
