Document Summary
Chapter 1 the chemical basis of life. Ability of a cell to carry out metabolic reactions to synthesize its constituents and to move, grow and reproduce requires input of energy. In all organisms, information specifying a cell"s structural composition and functional capacity must be faithfully maintained and transmitted each time the cell divides. Only a small subset of the known elements are found in living systems: most abundant of these are c, n, o, and h followed by ca, p, k, s, cl, na and. Mg: certain trace elements are also present in very small quantities. All molecules in a living organism contain carbon, so biochemistry is considered to be a branch of organic chemistry. Biological molecules are constructed from h, n, o, p, and s: the chemical reactivity of biomolecules is limited relative to the reactivity of all chemical compounds.
