Cell Membrane Transport
- Passive Transport
- Do not use energy
- Molecules move with concentration gradient.
- High to low.
- Diffusion
- Is the movement of
molecules in a fluid or
gas from a region of
higher concentration to a
region of lower
concentration.
- Osmosis
- Move across a
semipermeable
membrane from an
area of higher water
concentration to an
area of lower water
concentration.
- Facilitated Diffusion
- Is the diffusion of
molecules across a
membrane through
transport proteins.
- A concentration gradient is the difference
in the concentration of a substance from
one location to another.
- Active Transport
- Use energy
- Molecules move against concentration gradient.
- Active Transport
- Drives molecules across a
membrane from a region of
lower concentration to a
region of higher
concentration.
- Exocytosis
- The opposite of
endocytosis, is the release
of substances out of a cell
by the fusion of a vesicle
with the membrane
- Endocytosis
- Phagocytosis
- Is a type of
endocytosis in which
the cell membrane
engulfs large particles.Liquid Particles
- Pinocytosis
- Particles
solid
- Is the process of taking
liquids or fairly large
molecules into a cell
by engulfing them in a
membrane.
