Mn 2+ is very similar to Mg 2+ in terms of its chemical properties, including inner and outer shell complexation. Mn 2+ effectively binds ATP and allows hydrolysis of the energy molecule by most ATPases. Mn 2+ can also replace Mg 2+ as the activating ion for a number of Mg 2+-dependent enzymes, although some enzyme activity is usually lost. [56]

Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted to future generations.
