  1. Nitrogen -containing organic compound composed of bonded amino acid molecules whose functions are to serve as structural materials, energy sources, and chemical messengers. The four elements consist of carbon, hydrogen, oxygen, and nitrogen. The building blocks of these are amino acids
  2. Proteins that catalyze in living systems and also speed up specific chemical reactions without being consumed are?
  3. Organic compound that includes an amino group at one end and carboxyl group at the other which are also the structural unit of a protein molecule
    Amino acids
  4. This three dimensional structure of a protein is determined by its amino acid sequence, attractions, as well as repulsions between amino acids in different parts of the molecule
  5. This structure of a protein is the amino acid sequence of the polypeptide chain
    Primary structure
  6. Hydrogen bonding between oxygen and hydrogen atoms in different parts of the polypeptide chain determines this type of structure
    Secondary structure
  7. Hydrogen bonding and covalent bonding between atoms in different parts of a polypeptide can impact this level of folding to which structure?
    Tertiary structure
  8. This structure is formed when several polypeptide chains connect to form a very large protein
    Quaternary structure
  9. When this happens to a protein, it loses its tertiary or secondary structure of conformation. High temperature, radiation, pH changes, and certain chemicals such as urea can cause this to proteins.
  10. This is an organic compound that includes amino groups (-NH2) and a carboxyl group (-COOH). This is also the structural unit of a protein molecule.
    Amino group
  11. This monovalent group (–COOH) is the functional group in organic acids it is also bound to a hydroxyl group.
    Carboxyl group
  12. This group is bonded to a hydrogen atom and to another group of atoms called a side chain, or R group.
    Central carbon atom
  13. This group distinguishes one type of amino acid from another and makes them unique.
    R group
  14. This carries instructions that control a cells activity by encoding the amino acid sequences of proteins in its building blocks. The five elements of this are carbon, hydrogen, oxygen, nitrogen and phosphorus.
    Nucleic acids
  15. These are the building blocks of nucleic acids. Three of the parts it contains are a 5 carbon containing sugar, a phosphate group, and one of several organic bases.
  16. This contains sugar ribose and is a single polynucleotide chain. Its function is to use information stored in DNA to construct specific protein molecules.
    RNA (ribonucleic acid)
  17. This contains the sugar deoxribose and is a double polynucleotide chain. Its function is to store information for protein synthesis. This has the ability to make copies of or replicate its self.
    DNA (deoxyribonucleic acid)
