For example, ions take part in acid - base reactions that determine the formation and transport of environmental pollutants.

Most other nutrients, on the other hand, are more actively transported - there are certain receptors lining those intestinal cells (cells called enterocytes, if anybody cares) that pull salts, sugars, amino acids, etc. through the intestinal lining into the cells in exchange for other compounds (e.g. they'll pull in a hydrogen ion at the same time as an amino acid, then exchange the new hydrogen atom for a sodium molecule later.)

For example, while the Hybrid's lithium ion battery pack intrudes less into the trunk than the previous models, it still blocks the rear - seat pass - through, making it difficult to transport long or bulky items.

Genes putatively related to calcification (e.g. calcium and inorganic carbon transport, H + transport and carbonic anhydrases) have been identified via gene expression studies comparing calcifying and non-calcifying E. huxleyi cells [25 — 29], or in short - term experiments where calcification was regulated by limitation of ions needed for calcification (i.e. Ca2 +, HCO3 − / CO32 − [26,30,31]-RRB-.
