متابولیسم به انگلیسی metabolism, به فعالیَّت بیوشیمیایی در بدن جانداران گفته می‌شود که به آن توان «زندگی», «رشد», «بهبود», و «تولید مثل» را می‌دهد.

In a metabolic pathway, a specific molecule is altered in a series of defined steps, resulting in a certain product. Each step is catalyzed by a specific enzyme, a macromolecule that speed up a chemical reaction

Energy released from downhill reactions of catabolic pathways can be stored and then used to drive uphill reactions of anabolic pathways.

کاتابولیسم

کاتابولیسم به انگلیسی catabolism به پروسه تجزیه مولکول ها در موجود زنده گفته می‌شود.

Some metabolic pathways release energy by breaking down complex molecules to simpler compounds. These degradative processes are called catabolic pathways, or breakdown pathways.

آنابولیسم

آنابولیسم به انگلیسی anabolism به پروسه تولید مولکول های مورد احتیاج بدن گفته می‌شود.

Anabolic pathways, in contrast, consume energy to build complicated molecules from simpler ones; they are sometimes called biosynthetic pathways.
