Release of the solute from the binding site induces a conformational change that returns the protein to its initial shape. Some channel proteins are open all the time, but others are gated, meaning that the channel can open or close in response to a particular signal (like an electrical signal or the binding of a molecule). 2.The region of an enzyme called the active site has the shape and chemistry that fits one specific substrate molecule. Each individual substance in a solution or space has its own concentration gradient, independent of the concentration gradients of other materials, and will diffuse according to that gradient. In active transport, A. no energy input is required from the cell.
