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.
