| kingdom |
In biology, a kingdom or regnum is the top-level, or nearly the top-level, taxon of organisms in scientific classification. Originally two kingdoms were distinguished: the Animalia for animals, and the Vegetabilia or Plantae for plants. Early authors also treated minerals in a third kingdom Mineralia. Each kingdom was divided into classes, later grouped into phyla for animals and divisions for plants. ...

| kinetin |
Kinetin is a chemical plant hormone that promotes cell division. In some cases, kinetin acts together with another hormone, indoleacetic acid. The effect of kinetin (6-furfurylaminopurine), a substance which markedly promotes cell division in plant tissues, on mitotic activity of mouse jejunum mucosa after a single total body irradiation with 100 r of x rays was studied. ...

| kinase |
In biochemistry, a kinase is a type of enzyme that transfers phosphate groups from high-energy donor molecules, such as ATP, to specified substrates or target molecules; the process is termed "phosphorylation". Generally, the purpose of phosphorylation is to "activate" or "energize" a molecule, increasing its energy so it is able to participate in a subsequent reaction with a negative free energy change. ...
