ENDURING UNDERSTANDING ENE-2 Cells have membranes that allow them to establish and maintain internal environments that ere diferent
from their external environments.
LEARNING OBJECTIVE
ENE-2.A Desaribe the roles of each of the
components of the cell membrane in
maintaining the intemal environment of the cell.
Label the hydrophobic and hydrophilic
parts of one phospholipid.
There are three proteins embedded in the
membrane. Choose a color for
ESSENTIAL KNOWLEDGE
ENE-2.A.1 Phospholipids have both hydrophilic hydrophobic R groups
and hydrophobic regions. The hydrophilic
phosphate regions of the phospholipids are
oriented toward the aqueous external or
internal environments, while the hydrophobic
and hydrophilic R groups.
Color oode the regions of each protein.
Predict what would happen if a mutation
caused one of the hydrophobic R groups to
be switched with a hydrophilic R group.
Explain your thoughts:
fatty acid regions face each other within the
interior of the membrane.

membranes.
ESSENTIAL KNOWLEDGE
ENE-2B.1 Cell membranes consist of a structural
framework of phospholipid molocules that is
embedded wilh proteins, steroids (such as
cholesterol in eukaryates), glycoproteins. and
glycolipids that can fiow around the surface of the
cel within the membrane.
The tuid mosaic model states that the parts of the cell membrane
continually move past one another. If the diagram above were a
photo of a living cell membrane, drew a representation of that
same coll if you took another photo 20 minutes later. Add the same
three proteins to the diagram on the left.
