In this article, we will learn about secondary transport and try to answer the question is secondary transport active. Let us first understand what is secondary transport is.
Secondary transport is a type of transport at which the molecules will move from one to another side through facilitated diffusion and this happens in the presence of electrochemical potential.
Now see is secondary transport active and try to learn the facts around. There are 9 facts that we will learn in this article.
- How is secondary transport active?
- Does secondary transport need energy?
- How does secondary transport get energy?
- How does secondary active transport use ATP?
- Secondary transport function.
- How does secondary transport work?
- How is energy transferred in secondary active transport?
- Secondary transport cell.
- What is a secondary transport cell?
- Secondary transport cell example.
Let us understand the facts in detail and try to get the answer is secondary transport active.
How is secondary transport active?
The secondary transport is said to be an active transport because, in the active transport, the molecules or particles or solute move in both directions, or we can say in the opposite direction.
So, when we say secondary transport is active, the molecule undergoing that process will occupy active transport for movement.
Does secondary transport need energy?
As we know, in active transport, the molecules, particles, or solute material transfer from one side to another in the opposite direction.When this process occurs, there is a need for energy taken from ATP. ATP is an important energy factor for secondary transport.
How does secondary transport get energy?
During a means of active transport, ATP is required and this energy production occurs through a generation of a potential gradient which is known as an electrochemical gradient.
With the help of an electrochemical gradient, the energy is generated and this help in the transport of molecules, particles, and solute particles.
What happens is there are some ions in the cell membrane which undergo the pumping in and out process. Due to this pumping in and out process, there becomes a gradient which is an electrochemical gradient. In the end, this electrochemical gradient help in the production of energy which is in the form of ATP.
How does secondary active transport use ATP?
The role of ATP in active transport is not that much important. Normally, ATP undergoes the process of hydrolysis and hereby produces the energy for the transport of molecules, solutes, and particles.
When there is an electrochemical gradient, the ions, molecules, or solute moves according to the potential gradient and thereby the transport of ions, particles, or solute molecules occurs across the membrane.
Secondary transport function.
There is a various functions of secondary transport but there is some major function of secondary transport which are given below in the list.
- Help with the transport.
- Maintain equilibrium across the membrane.
- Energy production.
Help with the transport.
The secondary active transport mainly helps in the transport of molecules or ions of solute particles in both directions.
Maintain equilibrium across the membrane
Due to the electrochemical gradient, there is a generation of equilibrium across the membrane which helps the membrane retain its structure.
Energy production.
As we know that in the secondary transport the electrochemical gradient help in the transport of solutes, ions, or molecules due to which there is not no ATP used directly in the process.
How does secondary transport work?
The secondary transport is done by the transfer of molecules, ions, or solute particles by using a different types of energy not only ATP. The energy as we know mainly generated by the electrochemical gradient. This transport mainly occurs by two processes.
- Antiport
- Symport
The antiport also called as counter- transport. This type of secondary transport occurs by the transfer of molecules, ions, or solute particles occur in the opposite direction. This transport is also done sometimes when the concentration is high at ine side and low on another, so the transport occur from high to low concentrations.
Symport is also called as co-transport. As the name shows, there, the transport occurs from across the membrane in the same direction. It is sometimes transferred from low to high and high to low concentrations.
How is energy transferred in secondary active transport?
In the secondary active transport, there is normally no involvement of ATP is seen. Normally, the transport occurs across the membrane with the help of elan ectrochemical gradient.
In this type of transport, the molecules, ions, or solute particles moves against the electrochemical gradient. In this, the energy is taken by stored energy by primary active transport.
The process is done by two different process which are antiport and symport. In the process, there is a need of carrier protein which is also called as co transporter.
Secondary transport cell.
Those cells that are involved with the process of secondary active transport are called as secondary transport cell. These cell either take anti port type of transport of symport type of transport.
What is a secondary transport cell?
They are also called secondary transporters. These are the molecules that undergo the process of secondary transport and help in the transport of molecule, ions or solute particles across the membrane which is made up of lipid bilayer with the help of energy generated by electrochemical gradient.
Secondary transport cell example.
There are many examples of secondary transport cells. The list of examples is given below.
- H+ /Oligopeptide transporter
- Sodium-glucose cotransporter
- Glucose symporter SGLT1.
- Sodium- amino acide cotransporter
- NaHCO3 Cotransporter
- Sodium- Calcium exchanger
- Sodium/Phosphate cotransporter
Conclusion
At the last of this article, we can summarize that the process of secondary active transport is very different from passive active transport. In this process, the electrochemical gradient plays an important role to help in the transport of ions, molecules, or solute particles
