Expert Solution

The set of life-sustaining chemical reactions in organisms are known as Metabolism.The purposes of metabolism include extracting and storing chemical energy from substances obtained from the external environment, using stored chemical energy to drive unfavorable reactions in the necessary direction, converting food materials into building block precursors of biomolecules, assemble building block molecules into macromolecules, and the elimination of nitrogenous wastes.If all the reactions of the cell are allowed to reach equilibrium or if a metabolic equilibrium occurs in which metabolism is in a lowenergy level such that no change can happen without the input of energy, the cell dies.Organisms must maintain metabolic disequilibrium to allow for necessary reactions of life to occur.Thus it is not a purpose of metabolism.So the correct answer choice is:

Option e: allow all reactions of the cell to reach equilibrium.
