Identify the correct statement about cell membranes.
Cell membranes are made up of carbohydrates, lipids and proteins.
The correct answer is Cell membranes are made up of carbohydrates, lipids and proteins.
Cell Recognition: Carbohydrate chains (glycocalyx) on the outer surface act as markers for cell-cell recognition, important in the immune response and tissue formation. Intercellular Joining: Membrane proteins can connect adjacent cells, forming junctions that allow for communication or structural support. Enzymatic Activity: Some membrane proteins function as enzymes, catalyzing reactions at the membrane surface. The dynamic nature of the lipid and protein components contributes to the 'fluid' aspect of the fluid mosaic model, allowing the membrane to change shape and facilitating processes like cell movement and division.
