Understanding Facilitated Diffusion: Role of Carrier and Channel Proteins, Slides of Biology

Learn about facilitated diffusion, a passive transport process that utilizes carrier proteins to move lipid-insoluble substances across membranes. Discover the differences between carrier and channel proteins and their respective transport mechanisms.

FACILITATED
DIFFUSION
- is a type of passive transport
which relies on carrier proteins
in order for the substances to
move down their concentration
gradient.
- provides passage for certain
needed substances that are both
lipid-insoluble and too large to
pass through the membrane.

FACILITATED

DIFFUSION

  • is a type of passive transport

which relies on carrier proteins

in order for the substances to

move down their concentration

gradient.

  • provides passage for certain

needed substances that are both

lipid-insoluble and too large to

pass through the membrane.

Transport

proteins

  • act as a carrier.

It is needed as a

transport vehicle.

Carrier

Proteins

Integral glycoproteins which

bind a solute and undergo a

conformational change to

translocate the solute across

the membrane.

they have a much slower

rate of transport than

Channel Proteins.
