BIOS251 EXAMINATION 2026 VERIFIED
ANSWER BLUEPRINT
◉All the fluid and components between the nucleus and the cell
membrane; includes the cytosol as well as the cytoskeleton . Answer:
Cytoplasm
◉Phospholipid bilayer that surrounds all cells and regulates what
enters and leaves the cell; also provides protection for cells. .
Answer: Cell membrane (plasma membrane)
◉Plasma membrane layers composed of phospholipid molecules
arranged with polar heads facing the outside and nonpolar tails
facing the inside.
Contains Transmembrane proteins, Peripheral proteins, Cholesterol,
and sugar (glycolipids and glycoproteins) . Answer: Phospholipid
Bilayer
◉Integral proteins in the cell membrane, that extends all the way
through the membrane touching both the ICF and ECF . Answer:
Transmembrane Proteins
, ◉The proteins of a membrane that are not embedded in the lipid
bilayer; they are appendages loosely bound to the surface of the
membrane. . Answer: Peripheral Protein
◉Holds phospholipids still and can stiffen membrane . Answer:
Cholesterol
◉Does not use ATP as an energy source, occurs from high to low
concentration.
Includes: Simple diffusion, facilitated diffusion, and osmosis. .
Answer: Passive Transport
◉Moves along concentration gradient, from higher to lower
concentration . Answer: Simple Diffusion
◉The transport of substances through a cell membrane along a
concentration gradient with the aid of carrier proteins . Answer:
Facilitated Diffusion
◉Movement of water across semipermeable membrane from low
solute concentration to high solute concentration . Answer: Osmosis
