Methods of Absorption
Different methods of membrane
transport are used in epithelium
cells to absorb different nutrients
Simple Diffusion
Nutrients pass down the
concentration gradient
between phospholipids in
the membrane
Example: Hydrophobic
nutrients such as
fatty acids and
monoglycerides
...
Active Transport
Pinocytosis
Nutrients are pymped through
the membrane against the
concentration gradient by
specific pump proteins
Small droplets of the fluid
are passed through the
membrane by means of
vesicles
Example: Mineral
ions such as
sodium, calcium
and iron
