What is the other name for
the
CMB?
Fluid Mosaic Model
Passive Transport
• Does osmosis
or diffusion
require energy.
• No them move
along a
concentration
gradient
• http://pr
Facilitated Diffusion
• Facilitated
Diffusionmolecules move
down a
concentration
gradient with the
aid of special
proteins.
Active Transport
• Requires Energy
• ATP
• Moves against
the
concentration
gradient
Transporting
material
into a cell
by the in
folding of a
membrane.
Endocytosis
2 Types of Endocytoses
• PhagocytosesSolid particles are
ingested into the
cell
• Pinocytosis –
liquids taken into
the cell.
Exocytosis
• Moves
materials out
of the cell
