Cell Membrane Structure

Front

carbohydrate attached to a lipid; cell recognition

Back

glycolipid

Front

What provides stability and fluidity in cell membranes, becoming rigid in cold temperatures and too fluid in hot temperatures?

Back

cholesterol

Front

Permanently attached to the membrane; goes all the way through; signaling and transport cell processes

Back

integral protein

Front

Attaches only temporarily to the membrane; does not go all the way through the membrane; communication

Back

peripheral protein

Front

Transport protein; embedded in the cell membrane; provides hydrophilic passage for water and small polar ions

Back

channel protein

Front

Carbohydrate attached to a protein; immune system

Back

glycoprotein

Front

Short chains that attach to proteins and phospholipids

Back

carbohydrate

Front

Which of the following is not a major function of the cell (plasma) membrane?

• cell to cell communication
• provides a strong structure to keep the cell stiff and solid
• cell recognition
• controls the movement of substances in and out of the cell

Back

provides a strong structure to keep the cell stiff and solid
