Explanation:

Carbon is the element that forms the skeletal structure of all the organic biological compounds in the cells. Basically, the vast majority of essential molecules for the cell are composed of carbon. When Carbon is combined with other molecules like oxygen, hydrogen, Cabon forms essential compounds  for the maintenance of life, including sugars, alcohols, fats, aromatic esters, carotenoids etc. In fact the carbon composes the cell itself since it forms the basic structures of the cell membrane: Cholesterol, Phospholipids, Carbohydrates.
