Phospholipids, Cholesterol, Protiens
Major components of the palsma membrane
TERM 2
Hydrophilic heads and hydrophobic tails
DEFINITION 2
A phospholipid bilayer has ______ heads and _____ tails
TERM 3
Carrier Protien
DEFINITION 3
Requires glucose molecules and insulin to pass through this
membrane protien in the phospholipid bilayer;Passive
transport
TERM 4
Protien Channel
DEFINITION 4
requires water and ions to pass through this membrane
protien found in the plasma membrane;Passive transport
TERM 5
Solute Pump
DEFINITION 5
Requires a molecule of ATP in order to move particles across
the plasma membrane.Active transport
Diffusion, Osmosis,
Infiltration
Diffusion, Osmosis, InfiltrationThe three types of passive
transport mechanisms
TERM 7
Isotonic Solution
DEFINITION 7
Solution in which equal particle concentration inside and
outside the cell. No net movement.
TERM 8
Hypotonic Solution
DEFINITION 8
Solution in which there is a higher solute concentration inside
the cell than outside. Water follows higher particle
concentration and move into the cell, causing cells to lyse, or
explode.
TERM 9
Hypertonic Solution
DEFINITION 9
A solution in which a higher solute concentration exists
outside the cell than inside, Water follows t he higher particle
concentration and moves out of the cell. Can cause cell to
crenate, or shrink
TERM 10
glucose and insulin
DEFINITION 10
A carrier protien requires what to pass substances through
the plasma membrane?
Solvent
the main part of a solution; the liquid or gas in which the
solute is dissolved or suspended
