It is desired to model the growth of an individual bacterium. The cell transports S₁ into the
cell enzymatically, and the permease is subject to product inhibition. S₁ is converted into pre-
cursors, P, that are converted finally into the macromolecular portion of the cell, M. The cata-
lyst of all reactions is M.

Write the equations and define all symbols necessary to describe the changes in S₁, P, M, and
T within the cell. Remember that the cell volume is always changing.
