Document Summary
Friedrich wohler (germany: living cells & organisms were different from those in nonliving matter. Went against the laws of physics & chemistry: experiment: urea (biological origin) synthesized from ammonium cyanate (inorganic compound) Louis pasteur: fermentation to help french wine industry. Wine spoiled by bacteria during fermentation process. Yeas cells can convert sugars (grapes) to ethanol (wine: vitalism = biological reactions took place only through the action of a mysterious. Life force instead of physical or chemical processes. Sugar ethanol occurs only with living cells. Genes = control synthesis of enzymes involved: found in chromosomes, composed of proteins & nucleic acids. Dna primary bearer of genetic info (rna also: 2. 9x109 base pairs; >20,000 different genes. 1. 2 the elements & molecules of living systems. 1st tier = most abundant: chon, thermonuclear reactions produced heavier elements. First c, n, o then all other elements: chon important because of their strong tendencies to form covalent bonds.
