metabolic pathway

a series of consecutive biochemical reactions or steps through which digested food is transformed into basic nutrients such as amino acids, free fatty acids, and simple carbohydrates.

met·a·bol·ic path·way

(met'ă-bol'ik path'wā)
Intercellular chemical reactions; catalyzed by enzymes; include the principal chemical reactions, mostly enzyme-dependent, that an organism needs to maintain homeostasis and to break down or build up molecules.

metabolic pathway

the sequence of enzyme reactions followed in the formation of one substance from another.

Metabolic pathway

A sequence of chemical reactions that lead from some precursor to a product, where the product of each step in the series is the starting material for the next step.
