Anabolism

Definition

Anabolism is the set of metabolic pathways that construct molecules from smaller units, requiring energy input. It is essential for cell growth, repair, and differentiation.

5 Must Know Facts For Your Next Test

1. Anabolic processes are endergonic, meaning they consume more energy than they produce.
2. ATP is often used as an energy source in anabolic reactions.
3. Examples of anabolic processes include protein synthesis, DNA replication, and photosynthesis.
4. Anabolism works in contrast to catabolism, which breaks down molecules to release energy.
5. NADPH is a common reducing agent used in various anabolic reactions.
