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.

Cholesterol• 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

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