Water molecules combine with a hydrogen atom

A water molecule is removed as two molecules join together

Water molecules are added to split larger molecules

Hydrogen atoms are removed from molecules

Dehydration synthesis removes water; hydrolysis adds water

Dehydration synthesis adds water; hydrolysis removes water

Dehydration synthesis breaks down polymers; hydrolysis forms polymers

Dehydration synthesis and hydrolysis are the same process
