Ions in their gas-like state are highly reactive and will rapidly interact with ions of opposite charge to give neutral molecules or ionic salts. Ions are also produced in the liquid or solid state when salts interact with solvents (for example, water) to produce solvated ions, which are more stable, for reasons involving a combination of energy and entropy changes as the ions move away from each o… WebThe ions and molecules are moved across a biological membrane through certain transmembrane integral proteins. Because the transport is passive, it does not require direct chemical energy from ATP hydrolysis during the transport itself. Instead, these ions and molecules move down their concentration gradient while reflecting their diffusive nature.
