Chemistry writes the story of life.
Every cell, every second, it tells it again - powered by molecular design.
At the core of this process lies the citric acid cycle, the central hub of metabolism.
Here, acetyl-CoA derived from carbohydrates, fats, or proteins enters a precise series of reactions that convert fuel into energy.
Each step transfers electrons, drives ATP synthesis, and sustains the continuous renewal of life at the cellular level.
What may seem invisible is, in fact, the most constant motion in existence; the quiet rhythm of biochemistry that powers everything we do.
