What Are The Roles Of Carbohydrates Proteins And Cholesterol In The Plasma Membrane?

Carbohydrates, proteins, and cholesterol play essential roles in the plasma membrane's structure and function. Carbohydrates, often glycoproteins or glycolipids, are involved in cell recognition and signaling, facilitating communication between cells. Proteins serve various functions, including transport, acting as channels or carriers, and enabling enzymatic activity. Cholesterol helps maintain membrane fluidity and stability, ensuring that the membrane remains flexible and less permeable to certain substances.
