<prompt> Function of Metabolism includes all exceptExtraction of nutrients from foodBreakdown of substrateEquilibrium of biochemical with intracellular componentsUsing building blocks for synthesis  <response>: A i.e. Extraction of nutrients from foodExtraction of nutrients from food is not metabolism. Metabolism is oxidation of nutrients from food to produce energy.QMetabolism is a combination of two processes, namely:Anabolism : synthetic reactions that build up substancesCatabolism : reactions involving breakdown or oxidation of fuel molecules breakdown of substrateBoth catabolism and anabolism proceed only until equilibrium is achieved. Equilibrium is a mechanism for biological control of rate at which these reactions occur.
