Classification of active transport
What are the 3 types of active transport?
Types of primary active transporters
- P-type ATPase: sodium potassium pump, calcium pump, proton pump.
- F-ATPase: mitochondrial ATP synthase, chloroplast ATP synthase.
- V-ATPase: vacuolar ATPase.
- ABC (ATP binding cassette) transporter: MDR, CFTR, etc.
What are the types of active transport?
There are two main types of active transport: Primary (direct) active transport – Involves the direct use of metabolic energy (e.g. ATP hydrolysis) to mediate transport. Secondary (indirect) active transport – Involves coupling the molecule with another moving along an electrochemical gradient.
What are 2 types of active transport?
There are two types of active transport namely – Primary active transport and secondary active transport.
On what basis active transport is classified?
Primary Active Transport
Based on the transport mechanism as well as genetic and structural homology, there are considered four classes of ATP-dependent ion pumps: P-class pumps. F-class pumps. V-class pumps.
What is the characteristics of active transport?
During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient. Active transport is called “active” because this type of transport requires energy to move molecules.
What are the 4 types of transportation?
Air, Road, Sea and Rail. These are the four major modes of transport (or types) in the logistics industry.
What are the two types of active transport and how do they differ?
Active transport may be primary or secondary. A primary active transport is one that uses chemical energy in the form of ATP whereas a secondary active transport uses potential energy often from an electrochemical potential difference.
Which is the best example of active transport?
One of the greatest instances of active transport is the transfer of calcium ions out of heart muscle cells. Cells secrete proteins such as enzymes, antibodies, and a variety of other peptide hormones. Amino acid transportation occurs between the intestinal lining of the human gut.
What are the types of active and passive transport?
Examples of active transport include sodium-potassium pump, uptake of mineral ions by the roots of the plants, etc. Whereas, the examples of passive transport include the exchange of gases in the alveoli of the lungs and the exchange of nutrients in the kidneys.
What are the 4 types of passive transport?
There are four types of passive transport:
- Simple Diffusion.
- Facilitated Diffusion.
- Filtration.
- Osmosis.

What is example of secondary active transport?
An example of secondary active transport is the movement of glucose in the proximal convoluted tubule.
What is active transport in cell?
To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.
What are the 3 main differences between active and passive transport?
Difference between active and passive transport
| Active transport | Passive transport |
|---|---|
| Active transport is defined as the movement of molecules across the cell membrane by using cellular energy. | Passive transport is the movement of molecules across the membrane without the use of ATP. |
What are the 6 types of cellular transport?
Cell transport can be classified as follows:
- Passive Transport which includes. Simple Diffusion. Osmosis. Facilitated Diffusion.
- Active Transport can involve either a pump or a vesicle. Pump Transport can be. primary. secondary. Vesicle Transport can involve. Exocytosis. Endocytosis which includes. Pinocytosis. Phagocytosis.
