BIOCHEMISTRY C785 WGU MODULE 2 EXAM QUESTIONS
activation energy - CORRECT ANSWER - Energy needed to get a
reaction started
active site - CORRECT ANSWER - The binding platform part of an
enzyme for its specific substrate.
aggreggate - CORRECT ANSWER - Hydrophobic molecules Clump
together in a disorderly way
allosteric site - CORRECT ANSWER - A site on an enzyme other than
the active site, to which non competitive inhibitors bind, changing the
shape and activity of the enzyme.
alpha carbon - CORRECT ANSWER - the central carbon atom of each
amino acid
amino acid backbone - CORRECT ANSWER - The structure comprised
of the amino group, carboxyl group with a central alpha carbon atom.
amino group - CORRECT ANSWER - Consists of hydorgen and nitrogen
atoms (-NH3+)
, C-terminus - CORRECT ANSWER - the end of a polypeptide or protein
that has a free carboxyl group ( usually on the right)
carboxyl group - CORRECT ANSWER - A -COOH group, found in organic
acids.
catalyst - CORRECT ANSWER - substance that speeds up the rate of a
chemical reaction and remain unchanged from the reaction ( this is what
enzymes are)
Chaperones - CORRECT ANSWER - Helper molecules that assist in
protein folding of a newly made polypeptide
charged - CORRECT ANSWER - Amino acid has a positive or negative
charge
Competitive inhibitor - CORRECT ANSWER - Molecule that competes
with substrate to bind to the active site
degradation - CORRECT ANSWER - Protein is broken down back into
individual amino acids and recycled into other proteins.
Denaturation - CORRECT ANSWER - loss of normal shape of a protein
due to heat(hydrophobic interactions) , changes in pH(ionic/hydrogen
