Overview of ATP hydrolysis
- Glycolysis - where the simple sugar glucose is broken down. (Occurs in the cytosol) ATP hydrolysis happens here!
- The product from glycolysis is transformed for the next step. (Occurs in the mitochondria )
- The citric acid cycle - where energy precursors are made (Occurs in the mitochondria)
- Oxidative phosphorylation - this process uses the electron transport chain to produce the bulk of usable energy for the cell (Occurs in the mitochondria)
- ATP hydrolysis happens after the bulk of the energy is made in oxidative phosphorylation too!
What is ATP hydrolysis?
- Hydro - is greek for “water”
- Lysis - is greek for “to split”
|2 Water||1 hydronium ion|
|1 ATP||1 phosphoryl group|
|ENERGY!; ΔG = -30.5 kJ/mol of ATP|
Consider the following:
- Glycolysis and gluconeogenesis
- The citric acid cycle
- Oxidative phosphorylation
