Question

match each type of molecule with the description of its function in the cell membrane. not all options will be used.
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
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 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:

• Phospholipids: They form a bilayer which acts as a barrier between the inside and outside of the cell to regulate the interior environment.
• Peripheral membrane proteins: These are polymers that interact only with the surface of the cell membrane (either inside or outside) and have various functions.
• Cholesterol: It is a 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.

Answer:

• 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.
