Introduction.
SO, WHAT IS METABOLISM
ANYWAY?
Metabolism is a set of life-sustaining
chemical reactions in organisms. The three
main purposes of metabolism are:
a) The conversion of food to energy,to run
cellular processes.
b) The conversion of food/fuel to building
blocks for proteins, lipids, nucleic acid, and
some carbohydrates.
c) In the elimination of nitrogenous waste.
The word metabolism can also refer to the
sum of all chemical reactions that occur in
living organisms, including digestion and
the transport of substances into and
between different cells.
