In this process, the transport protein (often called a "pump") binds to adenosine triphosphate (ATP). Through a process called ATP hydrolysis, a phosphate group is removed from ATP, releasing energy. The transport protein uses this immediate energy to change its shape and ferry the molecule across the membrane.
Without the primary pump (the electric pump) filling the reservoir, the secondary turbine has no water flow and cannot work. In this process, the transport protein (often called
Active transport is divided into two main categories: and Secondary . While both require energy to move "uphill," they differ fundamentally in where that energy comes from and how it is applied. What is Primary Active Transport? Without the primary pump (the electric pump) filling
In biological terms, the sodium gradient established by the primary active transport (the Sodium-Potassium pump) creates a high concentration of sodium outside the cell. Sodium naturally "wants" to rush back in. Secondary active transport uses the kinetic energy of sodium moving down its gradient to power the movement of another molecule against its gradient.
