Metabolism consists of all the energy transformation reactions in an organism. c. Metabolism manages the increase of entropy in an organism. d. Metabolism specifically refers to the biochemical pathways involved in synthesis of macromolecules.

Metabolism consists of all the energy transformation reactions in an organism. (Ans. B)

Explanation:

Metabolism is defined as the total sum of the chemical reactions which synthesized in every cell of living things and provides energy for formation of new organic materials and vital processes (such as movement, growth, reproduction and development).

In living metabolism, enzyme mediated chemical reactions takes place. Energy which comes from nutrients and solar energy fueling multistep reactions and converting into the molecules which is necessary for maintenance and growth.
