active and passive transport

A net process of a molecule moving from a high concentration to low concentration.

Energy.

True.

Endocytosis.

Diffusion, osmosis, facilitated diffusion.

The movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

The process by which a cell expels materials in vesicles that fuse with the plasma membrane.

Transport proteins assist in the movement of substances across the cell membrane, either passively or actively.
