Chapter 5 membrane structure
and function exam review with
correct descriptions 2025 newest
Describe the fluid mosaic structure of cell membranes - Answer
The fluid mosaic model describes the structure of the plasma
membrane as a mosaic of components —including phospholipids,
cholesterol, proteins, and carbohydrates—that gives the
membrane a fluid character.
fluid mosaic - Answer Structural model of the plasma membrane
where molecules are free to move sideways within a lipid bilayer.
mosaic - Answer to something that contains many different parts
,cholestorol - Answer Liquid found in cell membranes. It belongs
to a group called sterols and it prevents inflexibility
extracellular space - Answer Everything outside the cell
lumen - Answer inside of the cell
lipid micelles - Answer bring fatty acids and lipid soluble
nutrients to the enterocyte apical membran
lipid bilayers - Answer The membranes found in human cells are
mostly
amphipathic - Answer Molecules are said to be this when it has
regions that are both hydrophilic and hydrophobic.
integral protein - Answer proteins implanted within lipid bilayer
of plasma membrane
peripheral proteins - Answer proteins that are outside of the lipid
bilayer on either side of the lipid bilayer
, carrier protein - Answer a protein that transports substances
across a cell membrane
protein channels - Answer pumps and channels that move
materials across the cell membrane
receptor proteins - Answer senses surroundings and reiceves
messages
channel proteins - Answer proteins that provide passageways
through the membrane for certain hydrophilic (water-soluble)
substances such as polar and charged molecules
cell recognition proteins - Answer Glycoprotein that helps the
body defend itself against pathogens.
enzymatic proteins - Answer accelerate the speed of chemical
reactions
glycoprotein - Answer short sugar chains attached to proteins
