Transport Notes
Objective: Figure out how things get in and out of the selectively permeable cell membrane
Transport
Passive: no energy required.
Molecules will move from high
concentration to low.
Diffusion: the
passage of
particle from
high to low
concentration
Hypertonic:
there is more
solute than
water
Osmosis: the
movement of
water molecules
across a
semipermeable
membrane.
Hypotonic:
there is more
water than
solute
Active: requires energy (ATP) requires
a transport protein and moves particle
from low concentration to high.
Facilitated
Diffusion: The
transport of
specific
particles
through a
transport
protein.
Isotonic: the
concentration
of water and
solute are the
same
Molecular
Transport:
transports
small
molecules and
ions using a
transport
protein.
Requires
energy
Endocytosis:
Engulfing large
particles.
(Phagocytosis):
Cell eating
Pinocytosis:
Cell drinking
What is equilibrium? An equal state.
Solute: any substance
that can dissolve in a
liquid.
Solvent: any substance
that dissolves solutes.
Exocytosis:
Releasing
large particles
outside of the
cell.
