What are 2 types of active transport?

Answer 1

A) Active transport through special transport proteins in the plasma membrane. ATP causes these proteins to change shapes and move materials from low to high concentration.

B) Bulk transport - moving large particles through the membrane by endocytosis or exocytosis.

Answer 2

Active transport happens when a cell is moving a substance using energy to move it against its concentration gradient.

One example is an ion pump channel in a cell membrane, which moves ions across the membrane.

Another example is endocytosis, where the cytoplasm surrounds a particle (phagocytosis) or liquid (pinocytosis), and forms a food vacuole.

The opposite of endocytosis is exocytosis (getting rid of materials), which is also an example of active transport.

Answer 3

Primary Active TransportIn this process, ions are moved across a cell membrane by carrier proteins that directly couple transport with hydrolysis of ATP. Co-transport (Secondary Active Transport)Transport across membranes can be fueled not only by ATP, but by the energy stored in ion gradients.

Answer 4

The two principle methods of active transport are ATP-driven active transport (e.g. Na+ - K+ ATPase) and ion gradient-driven active transport, as in the Na+ - glucose symport.

Answer 5

Endocytosis and Exocytosis but there are numerous others

endocytosis and exocytosis

Answer 7

Molecular transport and bulk transport.
