hydrolysis... my Biology book says that... cells dissasemble macromolecules into their constituent subunits by performing reactions that are essentailly the reverse of dehydration- a molecule of water is added instead of removed.
Macromolecules are assembled through the process called dehydration process( -OH and -H are removed as subunits are joined), and they disassembled through hydrolysis(- OH from water attaches to one subunit and -H from water attaches to the other subunit).
Macromolecules are disassembled in the types of reactions known as hydrolysis reactions. They release water during formation, which contributes more water and causes hydrolysis.
They are mainly hydrolysis. It adds a water molecule
Hydrolysis
Hydrolysis
The term that identifies a reaction that breaks apart macromolecules is "hydrolysis." In hydrolysis, water molecules are used to break the bonds holding macromolecules together, resulting in the formation of smaller molecules or monomers.
Hydrolysis is the opposite to condensation. A large molecule is split into smaller sections by breakinga bond, adding -H to one section and -OH to the other.The products are simpler substances. Since it involves the addition of water, this explains why itis called hydrolysis, meaning splitting by water.A-B + H2O --> A-H + B-OH

A lysis, though this term if prefered for cells destruction. For a molecule, you precise the kind of reaction : if the reaction imply water, it's an hydrolysis (for macromolecules, it usually is), but other kinds exists like hydrogenolysis.

what is the name for a reaction that links monomers to from a chain
This is a decomposition reaction.
reduction reaction
Macromolecules are linked with covalent bonds between its monomers. For example proteins are bonded with peptide bonds. Hydrolysis of these bonds will break them to small peptides and ultimately forms amino acids. For any other macromolecules the same hydrolysis is a key to separate them. This reaction is catalysed by enzymes.
Uranium-235
Uranium-235
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.
Lysosome, harbours hydrolytic enzymes that can work on & break down macromolecules like proteins etc into their monomers (amino acids) so that cells can reuse them.
