sodium.
Most cell membranes have a sodium-potassium pump. It is an enzyme that pumps sodium ions out of the cell and potassium ions into the cell. It moves 3 sodium ions out and 2 potassium ions in. Both ions are transported against the concentration gradient. Thus, the sodium-potassium pump provides one positive charge carrier to the extracellular space.

Explanation:
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
Answer:
Chemical bonds of ATP
Explanation:
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups
