Which structural features in hemoglobin is the primary, secondary, tertiary and quaternary structure?

In your own words, explain why hemoglobin is important in hematology.

A 37-year-old man whose respirations are being maintained by a mechanical ventilator has the following arterial blood volume: i. pH 7.50ii. PCO2 20 mm Hg iii. HCO3- 15 mEq/L Which of the following is also expected in this patient? a) Decreased intracellular pH b) Increased serum concentration of ionized calcium c) Increased serum concentration of potassium d) Increased urinary concentration of ammonium e) Increased urine pH

Give answer all questions with explanation

Identify the human form of hemoglobin that is produced only by the embryo. two a-globin chains (alpha) and two b-globin chains (beta) two b-globin chains (beta) and two g-globin chains (gamma) two g-globin chains (gamma) and two d-globin chains (delta) two d-globin chains (delta) and two e-globin chains (epsilon) two e-globin chains (epsilon) and two z-globin chains (zeta)

Which of the following is the cause of this type of anemia (A) lack of iron (B) lack of Vitamin B12 (C) lack of intrinsic factor (D) single amino acid substitution (glutamic acid replaces valine) (E) single amino acid substitution (valine replaces glutamic acid) (F) loss of bone marrow stem cells

How does the shape of red blood cells enable them to exchange gases and move through blood vessels more easily?

You are studying with a friend who is describing the Bohr effect. She tells you that in the lungs, hemoglobin binds oxygen and releases hydrogen ion; as a result, the pH increases. She goes on to say that in actively metabolizing muscle tissue, hemoglobin releases oxygen and binds hydrogen ion and, as a result, the pH decreases. Do you agree with her reasoning? Why or why not?
