What are the differences and similarities between diffusion, facilitated diffusion, osmosis and active transport?

Answer 1

That is heck of a long question brother

Diffusion is movement of molecules from an area of their higher concentration to area of their lower concentration.

Facilitated diffusion is movement of molecules from an area of their higher concentration to area of their lower concentration through a cell membrane with help of membrane bound protein channels or carrier proteins

Osmosis is movement of water molecules from an area of their higher concentration to area of their lower concentration through a semipermeable membrane.

Active transport is movement of molecules from an area of their lower concentration to area of their higher concentration using energy in form of ATP by pump proteins.

Answer 2

Diffusion:

  • Movement of molecules from an area of high concentration to low concentration.
  • No energy input required.

Facilitated Diffusion:

  • Movement of molecules through a cell membrane with the help of transport proteins.
  • No energy input required.

Osmosis:

  • Movement of water molecules across a selectively permeable membrane from an area of low solute concentration to high solute concentration.
  • No energy input required.

Active Transport:

  • Movement of molecules against their concentration gradient.
  • Requires energy input, usually in the form of ATP.
  • Involves specific carrier proteins.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
