- TL;DR Summary
- Generally it is said that all biological catabolic reactions are exergonic. But in chemistry it is said that breaking of bonds are considered endergonic and bond-forming is exergoic. It looks contradictory. What is the missing link?
Generally it is said that all biological catabolic reactions are exergonic. Famous example is ATP hydrolysis is exergonic. That's why it is called energy currency. Similarly breaking of glucose molecule into pyruvate also releases energy to form ATP.
But in chemistry it is said that breaking of bonds is endergonic. Famous example is water. The splitting of water is said to be endergonic (non-spontaneous) reaction, and thus would require energy (chemical work to be done) in order to happen.
The understanding from chemistry and biology seem to be contradictory to each other.
What is it, I am missing here?
Thanks.
