Question
1. Which of the following statements regarding classification and/or function of proteins is correct?
options:
a) An oligomeric protein implies that a protein has multiple alpha helices.
b) Hemoglobin is classified as a monomeric glycoprotein.
c) One of the functions of proteins is to store energy.Under conditions of excess protein/amino acid intake, amino acids can be stored as energy for later use.
d) The function of antibodies is to serve as protective proteins. Antibodies bind antigens with exceptional specificity. The specificity is driven by the complementary shape and polarity between the hypervariable domain of the antibody and antigen.
e) Collagen falls into the class of structural proteins. The strength of this molecule is largely the result of the presence of extensive beta pleated sheet.
2. Using the diagram below, determine the net charge of the peptide at pH 2. From this, select which of the following statements is correct.
options:
In an electrophoresis unit, the peptide will travel toward the anode at pH 2.
In an electrophoresis unit, the peptide will travel toward the cathode at pH 2.
At pH 2, this peptide will be neutral in charge and therefore will not move in an electrophoresis unit.
Not enough information is provided to determine the movement of this peptide in an electrophoresis unit under the specified conditions.
