Question

match each type of molecule with the description of its function in the cell membrane. not all options will be used. transmembrane proteins phospholipids peripheral membrane proteins cholesterol carbohydrates # lipid that modifies the fluidity and permeability of the membrane # polymers that interact only with the surface of the cell membrane, either inside or outside the cell, and have a variety of functions # polymers that cross the entire cell membrane, interacting with the interior and exterior of the cell, and have a variety of functions # polymers that interact only with cell membrane on the outside of a cell and have a variety of functions # a family of molecules that provide a barrier between the inside and outside of a cell so that nothing can move in or out # small polymers attached to the outside of cell membranes that provide energy for the cell # a family of molecules that provide a barrier between the inside and outside of the cell so that the interior environment of a cell can be regulated # small polymers attached to the outside of cell membranes that act as identification tags and signal to other cells

Explanation:

Transmembrane proteins are polymers that cross the entire cell - membrane, interacting with the interior and exterior of the cell, and have a variety of functions. Phospholipids are a family of molecules that provide a barrier between the inside and outside of the cell so that the interior environment of a cell can be regulated. Peripheral membrane proteins are polymers that interact only with the surface of the cell - membrane, either inside or outside the cell, and have a variety of functions. Cholesterol is a lipid that modifies the fluidity and permeability of the membrane. Carbohydrates are small polymers attached to the outside of cell membranes that act as identification tags and signal to other cells.

Answer:

Transmembrane proteins: Polymers that cross the entire cell membrane, interacting with the interior and exterior of the cell, and have a variety of functions
Phospholipids: A family of molecules that provide a barrier between the inside and outside of the cell so that the interior environment of a cell can be regulated
Peripheral membrane proteins: Polymers that interact only with the surface of the cell membrane, either inside or outside the cell, and have a variety of functions
Cholesterol: Lipid that modifies the fluidity and permeability of the membrane
Carbohydrates: Small polymers attached to the outside of cell membranes that act as identification tags and signal to other cells
