B1.1.1 Introduction to Biological Molecules Flashcards
Individual biological molecules that can be linked to form chains are called…
monomers
Which type of reaction take place every time a monomer undergoes polymerisation?
a condensation reaction
Which polymer do many mononucleotides form?
Polynucleotides
Name the common biological monomers
mononucleotides (or just nucleotides)
monosaccharides
amino acids
Describe a hydrogen bond
When the positive charge of one polar molecule is attracted to the negative charge of another polar molecule.
a hydrolysis reaction requires…
the addition of water to separate a polymer into its monomers.
What is meant by metabolism?
All of the chemical reactions that are taking place in the human body
The process of polymer formation from monomers is called…
polymerisation
What is a solute?
The solid that is dissolved to make a solution
Name 3 common biological polymers

Polypeptides (proteins)
Which polymer do many monosaccharides form?
Polysaccharides
a condensation reaction releases…
a water molecule when monomers join
Long chains of monomer sub units are called…
