Cell Membrane
Who am I?
• I am a protein molecule that is permanently attached or firmly anchored in the plasma membrane. I also serve as transport proteins, chemical receptors, and regulators for cell to cell recognition.
Integral proteins
• I am a protein molecule that is permanently attached or firmly anchored in the plasma membrane. I also serve as transport proteins, chemical receptors, and regulators for cell to cell recognition.
Who am I?• I attach to membrane proteins and serve as
identification tags, allowing cells to distinguish one type of cell from another. Cell recognition and cell signaling.
Carbohydrate chains• I attach to membrane proteins and serve as
identification tags, allowing cells to distinguish one type of cell from another. Cell recognition and cell signaling.

Who am I?
• I am a protein that is not embedded and is loosely attached to the surface of the cell membrane.
Peripheral Protein
• I am a protein that is not embedded and is loosely attached to the surface of the cell membrane.
Who am I?• I am found in animal cell membrane and effect
fluidity (how easily the structure can move) depending on temperature. I also strengthen the cell membrane.

Who am I?
• I am composed of three basic parts: a charged phosphate group and glycerol “head”, and two fatty acid chains “tail”.
Phospholipid
