Protiens which twist themselves to actively transport things in and out of the cellular membrane.
Endocytosis is the provess used by the cell to bring in large molecules.
large molecules and charged molecules move across a cell membrane through "facilitated diffusion." That is to say, a transport protein in the plasma membrane of the cell is used (with the aid of adenosine triphosphate, or ATP) to move the substance from one side of the membrane to the other.This method is actually the basis upon which all cell function is based, from generating and using energy, to keeping the cell isotonic to its environment.
Endocytosis (into the cell) and exocytosis (out of the cell) are used to transport molecules that are too large to get through the cell membrane otherwise.
I do believe that the answer is facilated diffusion.
2 ATP molecules are used to break the glucose molecule into two pyruvate molecules in the cytoplasm. Then the pyruvate travels to the mitochondria, where it is broken down further and produces 34 ATP molecules, which are used to power a cell.

Heat makes molecules move. Alcohol, if used as a solvent, makes some molecules more mobile.
Exocytosis is the process by which large molecules are transported out of the cell.

Without a cell membrane involved, this is just simple diffusion. If a cell membrane is involved, it is osmosis.
