Document Summary
Chapter 1 - biochemistry and the language of chemistry. Biochemistry seeks to understand the chemical basis for all life processes. Metabolic pathways are made up of linked sequences of two or more individual reactions: 2 the elements and molecules of living systems. Second generation of stars : life could come into being only when certain elements ( c , , hydrogen , oxygen , and primarily of carbon nitrogen (cid:8869) most abundant elements in the universe. The solvent properties of water are indispensable in biochemical processes. Third and fourth - tier elements are metals some of which serve as aids to the catalysts of biochemical reactions. Scientists hypothesize that a highly reducing environment prevailed within the primordial atmosphere (cid:8869) a condition that tends to promote joining reactions of atoms and molecules. High - energy discharges were thought to occur through lightning or volvanlc eruptions, providing sufficient energy to drive atoms and small molecules together.
