Active Transport Notes

The function of ATP is to provide energy for cells.

It moves molecules from high to low concentration without energy.

It moves molecules from low to high concentration using ATP.

It moves molecules from high to low concentration using ATP.

It moves molecules from low to high concentration without energy.

Uses ATP for energy

Molecules move against the gradient

Moves from high to low

Molecules move with the gradient

By moving sodium and potassium ions from high to low concentration

By moving sodium ions into the cell and potassium ions out of the cell

By using ATP to move sodium ions out of the cell and potassium ions into the cell

By allowing ions to diffuse freely across the membrane

Phagocytosis

Osmosis

They use ATP to move substances against the concentration gradient.

They move substances from low to high concentration.

They are a type of active transport.

They allow passive diffusion of molecules.

Exocytosis moves substances out of the cell, while endocytosis brings substances into the cell.

Exocytosis uses protein pumps, while endocytosis uses vesicles.

Exocytosis requires no energy, while endocytosis does.

Exocytosis only occurs in plant cells.
