Download Passive Transport foldable

Outside
Std. 2 Passive Transport
-Does not require energy
Diffusion
Facilitated Diffusion
Carrier Protein
Osmosis
Channel Protein
Facilitated Diffusion
Movement of molecules from a high
concentration to a low concentration using a
protein
Inside
of the
foldable
Carrier Protein
Changes shape to match the particle’s shape
and then carries it through the cell membrane
Channel Protein
Forms a channel that allows particles through
Isotonic Solution
The solute in the solution is EQUAL to the
solute inside the cell so water moves in and
out equally “ISO- means equal”
Hypotonic Solution
The solute in the solution is LESS THAN the
solute inside the cell so water enters the cell
“HYPO- means less”
Isotonic
Hypotonic
Hypertonic Solution
The solute in the solution is MORE THAN
the solute inside the cell so water leaves
the cell “HYPER- means more”
Hypertonic

Std. 2 Active Transport
-molecules move from low to high concentration
which requires energy!
Endocytosis
Diffusion
Movement of molecules from a high
concentration to a low concentration
Phagocytosis
Pinocytosis
Receptor-mediated
Exocytosis
Transport Proteins
Phagocytosis
Solid materials are engulfed;
AKA “cell eating”
Pinocytosis
Liquid materials are
engulfed; AKA “cell drinking”
Receptor-mediated
Molecules are received at
receptor sites that are
specific to those molecules
Exocytosis
Materials exit the cell; “exo-”
means exit
Transport Proteins
Act as gatekeepers of the
cell because they help
molecules enter and exit the
cell membrane
