Teens & Depression. â 1 Depression is a serious problem today and one of the nationâs leading killers of teenaged boys when the number of cases of suicide it generates are factored into the equation.
The first organic molecules were probably very simple carbon-based molecules made of few atoms. These molecules then combined with other simple molecules to form more complex molecules. Over many years and probably trillions and trillions of chemical reactions, more complex molecules, and more stable molecules, formed.
Carbon is a component of all organic molecules, many of which are essential for life. The ultimate source of all organic molecules is primary production, in which photosynthetic organisms take in carbon dioxide gas (or bicarbonate - CO2's water-dissolved form) and, using sunlight as an energy source, convert it into glucose.
