Cell Membrane Labeling Quiz

Study Notes

Cell Membrane Components

Hydrophobic Tail: Refers to the water-fearing part of a phospholipid, which avoids water and interacts with other hydrophobic substances.
Hydrophilic Head: Denotes the water-loving part of a phospholipid, which attracts water molecules and forms the outer layer of the membrane.

Membrane Proteins

Channel Protein (Integral Protein): Facilitates the movement of specific substances across the cell membrane, aiding in transport and communication.
Peripheral Protein: A protein that is not embedded in the lipid bilayer but instead is loosely attached to the membrane's surface, playing roles in signaling and structural support.

Lipid Structures

Glycolipid: A lipid molecule that has carbohydrate chains attached, contributing to cell recognition and signaling.
Cholesterol: A crucial lipid in the cell membrane that maintains membrane fluidity and stability, especially in varying temperatures.
Phospholipid Bilayer: Composed of two layers of phospholipids, this structure forms the basic framework of plasma and organelle membranes, providing a barrier between the cell's interior and external environment.

Identification and Signaling

Glycoprotein: A protein that has carbohydrate chains attached, involved in cell recognition and communication.
Carbohydrate Chain: Structures attached to proteins or lipids that function in cell identification, playing key roles in immune response and cell interactions.
