Has a Phosphate Group Removed?

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

Is a phosphate group added or removed?

A phosphate group is removed from an intermediate reactant in the pathway, and the free energy of the reaction is used to add the third phosphate to an available ADP molecule, producing ATP (Figure 2). This very direct method of phosphorylation is called substrate-level phosphorylation.

What is the removal of a phosphate group called?

From Wikipedia, the free encyclopedia. In biochemistry, dephosphorylation is the removal of a phosphate (PO₄³⁻) group from an organic compound by hydrolysis.
