Question

match each molecule to its function in the cell membrane. proteins carbohydrates lipids function molecule allow the cell to be recognized by other cells give the membrane its flexibility pump large molecules across the membrane submit work it out not feeling ready yet? these can help: animal cell diagrams: label parts (100) structure and function: lipids (95)

Explanation:

• Carbohydrates: In the cell membrane, carbohydrates are often attached to proteins or lipids. They play a crucial role in cell - cell recognition. For example, in the immune system, immune cells recognize "self" cells based on the carbohydrate - protein complexes (glycoproteins) or carbohydrate - lipid complexes (glycolipids) on the cell membrane.
• Lipids: The cell membrane is mainly composed of a lipid bilayer (phospholipids). The fatty acid tails of phospholipids are non - polar and can move relatively freely, which gives the membrane its flexibility.
• Proteins: There are different types of membrane proteins. Transport proteins (such as carrier proteins and channel proteins) can pump large molecules (for example, glucose is transported into cells by carrier proteins) across the membrane.

Answer:

• allow the cell to be recognized by other cells: carbohydrates
• give the membrane its flexibility: lipids
• pump large molecules across the membrane: proteins
