This course introduces the ways molecules are transported through cell membranes and communicate within and in between cells, as well as the principles of biosynthesis in living cells. Topics include: transport of biomolecules and ions across cell membranes, signal transduction, regulation of metabolic pathways, anabolic pathways (e.g., carbohydrate, lipid, protein and nucleic acid biosynthesis). Prerequisites CH350. Exclusions CH353.
