How are cells able to transport large molecules?
Large molecules enters a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell.When a portion of the cell membrane folds in on itself, encircling extracellular fluid and various molecules or microorganisms. The resulting vesicle breaks off and is transported within the cell.
If the particle is solid, endocytosis is also called phagocytosis. If fluid droplets are taken in, the processes is called pinocytes.
