Catabolic-Anabolic Steady State
Catabolic reactions that break complex molecules provide the energy needed by anabolic reactions to produce complex molecules.
Absorptive State
When the gastrointestinal tract is full, anabolism exceeds catabolism; this is the absorptive state.
Postabsorptive State
The post-absorptive state occurs around three to five hours after a meal has been completely digested and absorbed.
