Carbohydrates
Respiratory substrates which provide energy for cells, also used for structure in cell membranes and cell walls in plants
Lipids
Can be used as respiratory substrates which provide energy for cells, form a bilayer in cell membranes and make up some hormones
Proteins
Main component of many cellular structures, form enzymes and chemical messengers
Nucleic acids
Form polymers (DNA and RNA) which make up the genetic material of organisms. Code for the sequence of amino acids which make up all proteins
Condensation reaction
A condensation reaction joins two molecules together with the formation of a chemical bond and involves the removal of a molecule of water
Monomers and polymers
Monomers are small or repeated molecules which can be joined together to make larger molecules called polymers.
Monomers are joined together into polymers by condensation reactions
Hydrolysis reaction
A hydrolysis reaction breaks a chemical bond between 2 molecules with the addition of a water molecule
