Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells. Reaction consumes the electrode during discharge and regenerates it during charge. Protein structure has four levels: primary, secondary, tertiary (globular) and quaternary. To call this process secondary active transport is appropriate since the existence and maintenance of the concentration gradient of the driving ion is accomplished by primary active transporters (i.e., pumps). Active transport: moving against a gradient. The folding of a protein chain is, however, further constrained by many different sets of weak noncovalent bonds that form between one part of the chain and another. The cells are with plenty of cytoplasm and prominent nucleus. Sodium serves as the driving ion in many (but not all) secondary active transporters located in the plasma membrane of various cells.
