UNE Medical Biochemistry Midterm Review Already Graded A A family presents for genetic counseling. The couple has two female children who are alive and well; however, their infant son recently died in the nursery with severe hemolysis (lysis of red blood cells) and jaundice. The wife recalls she lost a brother in infancy with severe hemolysis, induced after a viral infection. The physician suspects a glucose-6-phosphate dehydrogenase deficiency, this would result in a deficiency in which of the...

Hemoglobin binds oxygen with a greater affinity in the: correct answer: R state Hemoglobin bound to heme is termed a holoprotein. The heme or porphoryin ring is required for oxygen binding and it is termed a: correct answer: prosthetic group Alpha helices and beta sheets are primarily stabilized by: correct answer: H bonding Ligases are a class of enzymes characterized by their ability to: correct answer: synthesize bonds between carbon atoms and an additional atom that is involved ...

Proline. It is considered a 'helix breaker' and would not be found in an alpha helix; all other residues are nonpolar hydrophobic and could reside in a transmemebrane domain. Changes in the physiological variables listed below can alter the affinity of hemoglobin for oxygen. Which of the fol...

ligand - Is the word for a drug or a bio molecule a molecule that is reversibly bound to a protein, examples oxygen, endogenous neurotransmitters, hormones, drug molecules Binding site - A discrete portion of the protein that is complementary to the ligand in: - Shape and size - Charge distribution - Hydrophobic and hydrophilic regions ***Is involved in specific interaction, certain structural features must be present on the ligand for binding Induced fit - A complementary conformationa...
