Question

Dephosphorylation occurs when ATP molecules convert into ADP molecules. true or false

Answer 1

The dephosphorylation of ATP follows the formula:

ATP4- + H2O --> ADP3- + Pi

Where Pi indicates the phosphate ion, H2PO4

The standard Gibbs free energy for the reaction (delta G'o) = -30.5 kJ/mol, indicating dephosphorylation is spontaneous under standard conditions.
The equilibrium constant for the reaction (Ka) = [ADP][Pi]/[ATP] = 2.0 x 105 moles/L.
