Description: Describes a typical, active, living cell; the methods by which it is built up of chemical elements; and the way it carries on its functions through the release of chemical energy. Points out cell organelles and their functions emphasizing the pattern of energy changes and the dependence of the cell on its outside environment. Mentions atomic structure, compounds, and bonding characteristics as they apply to cellular activity. Shows the minute size of molecules compared with a water drop, a paramecium, and mitochondria. Relates the importance of high and low energy phosphate bonds in providing for many cell reactions. Illustrates how molecules build up organelles through PGAL to glucose and maltose, and how they organelles are operated by chemical energy released from chemical bonds.
