Anabolism
Dehydration synthesis: removal of a water molecule to create a bond between two separate molecules.
Phosphorylation: removal of a water molecule to create a larger molecule in cases where a phosphate ion is present.
Coupled reactions, opposites of each other.
Phosphorylation
and hydrolysis
Decarboxylation: removal of a carboxyl group to form a larger compound.
Phosphorylation
and decarboxylation
Loss of oxygen
Oxidation and reduction
Catabolism
Hydrolysis: Breaking down a larger molecule by adding a water molecule.
Opposite reactions, reversable.
Hydrolysis: breaking down of a larger molecule by adding a water molecule.
Phosphorylation: addition of a phosphate group to a molecule to break it down into smaller components.
Addition or removal of a group.
Gain of oxygen
Molecule gaining or losing hydrogen or oxygen.
