When molecules are actively leaving and entering cells, this process is called active transport. It is the only way of transportation that involves energy.
there is no requirement of energy for this motion so it is a passive process
Carrier proteins are sometimes used during passive transport.
They both transport proteins and molecules across the cell membrance. Each have 3 different types within themselves. There aren't very many similarities. They function in different ways.
Some molecules are too large to pass through the cell membrane without transport proteins.
the Endoplasmic reticulum
diffusion- passive transport in cells where molecules move from an area where there are more molecules to an area of fewer molecules.
active transport by endocytosis
phagocytosis
Cellular transport is one of the cells' most vital functions. It allows cells to receive molecules and atoms into the cell as well as sending out molecules and atoms.
Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.

Carrier proteins are sometimes used during passive transport.
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
