alive is no easy business. To keep from dying, cells
must constantly juggle a wide range of tasks. They need to turn
food into energy and produce the proteins and enzymes that choreograph
crucial life processes. But no matter how efficient a cell is, in
the end, it will die. To make sure its work does not die with it,
every cell must be able to reproduce. This chapter reviews cellular
respiration, protein synthesis, and cellular reproduction, the three
crucial cellular life processes.
