BIOCHEMISTRY C785 WGU MODULE 2
EXAM WITH COMPLETE SOLUTIONS
amino group - Correct Answers -Consists of hydorgen and nitrogen atoms (-NH3+)
carboxyl group - Correct Answers -A -COOH group, found in organic acids.
R group - Correct Answers -a functional group that defines a particular amino acid that
makes it a specific protein (20 amino acids) aka side chain
alpha carbon - Correct Answers -the central carbon atom of each amino acid
amino acid backbone - Correct Answers -The structure comprised of the amino group,
carboxyl group with a central alpha carbon atom.
Hydrophobic - Correct Answers -non polar, afraid of water
polar - Correct Answers -Amino acid Molecule with partial charges. Mixes with water.
charged - Correct Answers -Amino acid has a positive or negative charge
Polypeptide - Correct Answers -A single protein chain formed by amino acids bonded
together
peptide bond - Correct Answers -The chemical bond that forms between the carboxyl
group of one amino acid and the amino group of another amino acid by dehydration ( In
which a water molecule is removed, C-N bond)
Hydrolysis - Correct Answers -Peptide bonds can be broken by this...A chemical
process that splits a molecule by adding water. ( this happened frequently in the
stomach when proteins begin to bee digested into their amino acids)
Substrate bonding affinity - Correct Answers -Attraction of substrate to the active site of
an enzyme
phosphorylation - Correct Answers -Kinase- Attachment of a phosphate group of a polar
amino acid to modify a protein to regulate enzyme activity
Dephosphorylation - Correct Answers -Phosphatases- Removal of a phosphate group of
a polar amino acid to modify a protein to regulate enzyme activity
