Moving sodium and potassium ions actively transported across the cell membrane against the concentration gradient. An active transport process involves expense of energy. The energy comes by hydrolysis of ATP. It involves an enzyme called Na+/K+-ATPase. This process is responsible for maintaining the excess of Na+ outside the cell as well as the excess of K+ ions on the inside. There is transport of three Na+ to the outside of the cell and the transport of two K+ ions to the inside. This unbalanced charge transfer contributes to the separation of charge across the membrane. The sodium-potassium pump is an important for action potential.
1) By breaking of ATP to ADP
2) The sodium and potassium ions are transported using active transport process!
In cell, the movement of ions across the membrane at the expense of energy is known as Active Transport. The energy is used in the form of ATP(Adenosine Triphosphate) that gets converted to ADP(Adenosine diphosphate) during transport. It takes the ions from high concentration to low concentration. ADP contains one less phosphate group that ATP, as their name indicates and plays a prime role in the flow of energy to the cells.
1: The ions are transported using a pump, which obtains energy by the breaking of ATP.
2:This action requires the expense of energy. So, sodium and potassium ions are transported using Active transport.
The mechanism described in the question, in which muscles of the body are contracted through the process of active transport.
The process needs input of energy because it involved movement of potassium and sodium ions against the concentration gradient. The energy is obtained by the breakage of ATP bonds to make the process possible.
Active transport can occur through two ways:
In this way, ATP molecule is directly used for the transportation of molecules across a membrane.
In which ATP is not directly involved in pumping or ions across the membrane.
Hope it help!
Answer is: active transport.
In active transport because energy is required to move the sodium and potassium ions against the concentration gradient. There is two type of active transport:
1) Primary active transport directly uses metabolic energy (adenosine triphosphate- ATP) to transport molecules across a membrane.
2) In secondary active transport (coupled transport) there is no direct coupling of ATP, energy derived from the pumping of protons across a cell membrane.
The ions are transported with the help of sodium-potassium pump that obtains energy by the breaking of ATP. This form of transportation is known as active transport.
In the active form of transportation, energy is needed to mediate the ions of sodium and potassium against the concentration gradient. There are two forms of active transport, that is, primary active transport and secondary active transport. In primary active transport energy in the form of ATP is used directly to conduct ions across a membrane, and in secondary active transport, no direct coupling of ATP takes place, however, in this energy is obtained due to the pumping of protons across the membrane.
The sodium and potassium ions are transported using a sodium potassium pump the process of moving sodium and potassium ions across the cell membrane.
