metabolismChemical processes of living organisms enabling them to grow and to function. It involves a constant alternation of building up complex molecules (anabolism) and breaking them down (catabolism). For example, green plants build up complex organic substances from water, carbon dioxide, and mineral salts (photosynthesis); by digestion animals partially break down complex organic substances, ingested as food, and subsequently resynthesize them for use in their own bodies (see digestive system). Within cells, complex molecules are broken down by the process of respiration. The waste products of metabolism are removed by excretion. |

| Conrad's test can determine whether a healthy balance is being maintained within the body's ability to repair DNA damage as it occurs (either as a normal by-product of cellular metabolism, or due to increased oxidative stress from unhealthy diet and lifestyle habits). In 1994, Eidelberg visualized cellular metabolism by measuring fluoro-deoxy-glucose (FDG), which cells take up when they're active. In the Phase I effort, Genomatica successfully demonstrated the use of its models of cellular metabolism to predict gene expression patterns in yeast, an important research organism. |
