Question:
Fill in the blank:
The transmission of information from one side of the membrane to the other using membrane proteins is called _____.
Gradient Formation
The generation of a gradient depends on the relative concentration of a specific molecule from one region to the next. The difference in concentration can occur as a result of multiple conditions that occurs inside the body system. The generation of a gradient is very important so that the movement of the chemicals can take place. The difference is observed between the cell cytoplasm and extracellular fluid.
