    Nitrogen is essential in building all amino acids. Proteins, made from amino acids, are used both in the metabolic processes and in the physical structure.

    Nitrogen is also part of the porphyrin ring that is essential to molecules like hemoglobin and the pigment chlorophyll.

    Nucleic acids in DNA & RNA have nitrogen in the molecules.

    Nitrogen is one of the 6 most common elements in an animals body but oxygen, hydrogen and carbon are the top three elements in a body.

    Sure. Nitrogen is a key of life.

    And so are carbon, hydrogen, oxygen, sulfur, and phosphorous, and . . .

    It's hard to choose just one element that is the "key to life," however, nitrogen is a key component of DNA, so it's safe to say life as we know it could not exist without nitrogen.

    You should worry about English skills before learning about biology and chemistry.

    There is no 'key' to life- life is a product of a combination of many different compounds, the vast majority of which use oxygen for respiration. Even fish breathe oxygen- their gills separate it from water.

    You could consider hydrogen to be a huge part in life, too, as it's the most abundant element in existence...
