Significance of metabolic rate.
METABOLISM is recognised as an aggregate of chemical processes providing vital functions of our organism. Chemical reactions taking place in our body are carried out in two main opposite directions: synthesis of complex substances from simpler ones (a n a b o l i s m or growth) and decomposition of complex substances into simpler ones (c a t a b o l i s m or disintegration).
Lots of systems take part in metabolism providing it with the most complex regulation at all its levels. During metabolism those substances that came into our organism are transformed into its own tissue substances and terminal products that are excreted from our body. All these transformations are followed by energy absorption and release.
Metabolism can have such form when the processes of energy absorption and release are equal to each other or such forms when one of them is prevailing.
