Question

8/29 cfu - cells, cell membrane and transport (l)
which statement best describes how large particles and macromolecules enter cells?
they dissolve in the extracellular fluid and are carried through the plasma membrane by osmosis
they pass through the plasma membrane by facilitated diffusion against the concentration gradient
they react chemically with lipids in the plasma membrane to make holes that are repaired by osmosis.
they are carried into the cell via endocytosis in a vesicle made from the cell membrane and then released

Explanation:

Osmosis is for water - not large particles. Facilitated diffusion is for small molecules and follows the concentration gradient. Chemical reactions to create holes is not a typical way for large particles to enter. Endocytosis is the process by which large particles and macromolecules are taken into the cell in a vesicle formed from the cell membrane.

Answer:

They are carried into the cell via endocytosis in a vesicle made from the cell membrane and then released
