Abstract
Life as we know it is based on carbon. The giant molecules that are characteristic of living things - polysaccharides, proteins and nucleic acids are all long chains of carbon containing units. The small molecules - such as amino acids and ATP - are also made of carbon. But carbon is not a static constituent of life - it travels to and fro throughout the biosphere; its comings and goings are known as The Carbon Cycle.
