Title: Endocytosis/phagocytosis
Post by: shininay on March 17, 2013, 10:04:40 pm

I'm very confused about the difference between the two! Also, in reference to a food particles which would you use?

Endocytosis refers to the bulk transport of material into the cell.

Phagocytosis refers to the bulk transport of solid material into the cell.

Therefore you would use phagocytosis in reference to food particles.

I was taught what Bad Student said. and that Phagocytosis is a subset of endocytosis

Yeah,
phagocytosis- bulk transport of solids
Pinocytosis- transport of liquids
Endo/Exocytosis- into and out of transport respectively.
Easy sum up.

Vesicular transport is the bulk transport of a substance by engulfment into or out of a cell, with the use of energy ATP.

Endocytosis is the active, bulk transport of materials by engulfment into a cell. There are two forms of endocytosis:
(a) Phagocytosis: the engulfment of solid particles.
(b) Pinocytosis: the engulfment of particles in dissolved solution form.

So ultimately, phagocytosis is a type of endocytosis. Just like the difference between chocolate cake and cake. Choc cake is a type of cake. :)
