Primary Secondary Active Transport !!better!! Info

The transport protein acts as an enzyme (an ATPase) that catalyzes the hydrolysis of ATP. When the bond of the third phosphate group is broken, a burst of energy is released. This energy causes the transport protein to change its physical shape, physically pushing the target molecule through the membrane. The Classic Example: The Sodium-Potassium Pump (

In primary active transport, energy is derived from the hydrolysis of ATP (adenosine triphosphate). primary secondary active transport

There are two main types: Primary and Secondary Active Transport. The transport protein acts as an enzyme (an

: This process creates an electrochemical gradient , which stores potential energy. 2. Secondary Active Transport The Classic Example: The Sodium-Potassium Pump ( In

Secondary active transport is a bit more clever. It doesn't use ATP directly. Instead, it hitches a ride on the energy created by primary active transport. How it Works
