What is the term for the removal of a phosphate group from a molecule?
APhosphorylation
BDephosphorylation
CDecarboxylation
DDehydrogenation
Answer & Solution
Correct answer: B. Dephosphorylation
1. Dephosphorylation is the removal of a phosphate group from a molecule.
2. Releasing one or two phosphate groups from adenosine triphosphate in this way releases energy.
3. Phosphorylation is the opposite move, the addition of a high-energy phosphate to a compound.
4. Decarboxylation removes a carboxyl group as carbon dioxide, which is a carbon change rather than a phosphate one.
