What pump does active transport use?

What pump does active transport use?

sodium-potassium pump
The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source. That source is adenosine triphosphate (ATP), the principal energy-carrying molecule of the cell.

What are the 4 types of active transport?


  • Antiport Pumps.
  • Symport Pumps.
  • Endocytosis.
  • Exocytosis.

What is transport and its types?

The different modes of transport are air, water, and land transport, which includes Rails or railways, road and off-road transport. In general, transportation is used for moving of people, animals, and other goods from one place to another.

What is an example of primary active transport?

Uptake of glucose in the human intestines is an example of primary active transport. Other sources of energy for primary active transport are redox energy (chemical reaction such as oxidation and reduction) and photon energy (light).

Which is an example of primary active transport?

Sodium-potassium pump, the most important pump in the animal cell is considered as an example of primary active transport. In this process of transportation, the sodium ions are moved to the outside of the cell and potassium ions are moved to the inside of the cell.

How is active transport performed in a protein pump?

In this type of active transport, the protein pump does not use ATP itself, but the cell must expend ATP in order to keep it functioning. This will be explained in more depth in the section on Symport Pumps below. Lastly, active transport can be accomplished through processes called endocytosis and exocytosis.

How is active transport different from passive transport?

In active transport, unlike passive transport, the cell expends energy (for example, in the form of ATP) to move a substance against its concentration gradient.

How does active transport work in living cells?

Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes.
