1.1 BM intro

• What are biological molecules?

  A particular group of chemicals that are found in living organisms.
• What are 3 ways atoms can combine/bond with each other?

  1. Covalent bonding
  2. Ionic bonding
  3. Hydrogen bonding
• In a covalent bond atoms share a pair of electrons in their outer shells.
• In ionic bonding, ions with opposite charges attract one another. Also known as an electrostatic attraction.
• What is the name of a molecule with an uneven distribution of charge?

  Polar molecule
• Although each hydrogen bond is individually weak, they can collectively form important forces that alter the physical properties of molecules. An example of this is water.
• Name an example that is bonded by hydrogen bonds.

  Water
• True or false, covalent bonds are stronger than ionic bonds?

  True
• True or false, ionic bonds are stronger than covalent bonds?

  False
• what is a monomer?


  A monomer is a molecule that can join together with other monomers to form a polymer.
• what is a polymer?


  A polymer is a large molecule made up of repeating subunits called monomers.
• name 3 biological molecule examples of monomers and what polymers they create
