Cell Transport
- Types of transport
- Passive Transport
- The movement of
materials across the
cell membrane without
using cellular energy
- Diffusion
- The process by which
particles move from an
area of high concentration
to an area of lower
concentration.
- The process by which
particles move from an
area of high concentration
to an area of lower
concentration.
- Facilitated
Diffusion
- The process in
which molecules
that cannot
directly diffuse
across the
membrane pass
through special:
- Protein Channels.
- This happens
because proteins in
the cell membrane
act as carriers, or
channels, making it
easy for certain
molecules to cross.
- Protein Channels.
- The process in
which molecules
that cannot
directly diffuse
across the
membrane pass
through special:
- Osmosis
- Diffusion of
water through a
selectively
permeable
membrane
- Aquaporins:
- Water channels
that allow water
to pass right
through the
channel proteins.
- Water channels
that allow water
to pass right
through the
channel proteins.
- Isotonic
- The
concentration of
solutes is the
same inside and
outside the cell.
- The
concentration of
solutes is the
same inside and
outside the cell.
- Hypertonic
- The solution has
a higher solute
concentration
than the cell.
- The solution has
a higher solute
concentration
than the cell.
- Hypotonic
- The solution has
a lower
concentration
than the cell.
- The solution has
a lower
concentration
than the cell.
- Diffusion of
water through a
selectively
permeable
membrane
- The movement of
materials across the
cell membrane without
using cellular energy
- Active Transport
- Molecular
Transport
- Small molecules and
ions are carried
across membranes
by proteins in the
membrane that act
like pumps.
- Small molecules and
ions are carried
across membranes
by proteins in the
membrane that act
like pumps.
- Bulk
Transport
- Large molecules
and solid clumps
of material are
transport by
movements of the
cell membrane.
- Exocytosis
- Cells release
large amounts of
material.
- Cells release
large amounts of
material.
- Endocytosis
- Is the process
of taking material
into the cell.
- Is the process
of taking material
into the cell.
- Large molecules
and solid clumps
of material are
transport by
movements of the
cell membrane.
- The movement of
materials against a
concentration
difference.
- Molecular
Transport
- Passive Transport
- Calssification according
to the requirement of
energ
- Passive Transport:
without using celular
energy.
- Active Transport
requires energy
- Active Transport
requires energy
- Passive Transport:
without using celular
energy.
