25. What level of protein structure does hemoglobin have that is not
found in myoglobin?
1. primary
2. secondary
3. tertiary
4. quaternary
10. Even though the amino acid sequence between subunits of
hemoglobin and myoglobin are not exactly the same, there are other
similarities between the two proteins. Which level of protein structure
differs when comparing myoglobin to hemoglobin?
1. Primary
2. Secondary
3. Tertiary
4. Quaternary
43. As carbon monoxide binds to hemoglobin, the protein subunits
change conformation to allow carbon monoxide to bind faster. This
process is called __________.
1. noncompetitive inhibition
2. allosteric binding
3. positive cooperativity
4. competitive inhibition
1. Which of the following accurately describes the functions of
hemoglobin and myoglobin?
1. Hemoglobin transports oxygen, Myoglobin stores oxygen.
2. Hemoglobin stores oxygen, Myoglobin transports oxygen.
3. Hemoglobin transports CO2 and Myoglobin stores CO2
4. Myoglobin transports CO2 and Hemoglobin stores CO2
7. Hemoglobin and myoglobin proteins bind molecular oxygen. The
protein subunit of hemoglobin does not bind directly to the oxygen.
Instead, a specific atom binds oxygen. In hemoglobin, which of the
following will directly bind oxygen?
1. Histidine
2. Heme
3. Carbon Monoxide
4. Iron
, 54. Which of the following also describes an "basic" condition?
(Choose all that apply.)
1. low pH
2. high pH
3. low H+
4. high H+
5. low protons
6. high protons
20. Which one of the following statements about the graph is
accurate?
1. The T state of hemoglobin is favored by low pH and induces the release
of oxygen
2. The R state is the prevalent form of hemoglobin at low pH
3. The R state is favored by the low pH and induces the binding of oxygen
4. The T state of hemoglobin is favored by high pH and induces the
release of oxygen
32. Acidosis occurs as a result of cardiac arrest. Which of the
following is the theoretical reason why sodium bicarbonate might be
administered to your patient during a cardiac arrest?
1. The bicarbonate acts to decrease pH, which enables hemoglobin to
enter the T state and more effectively deliver oxygen to the tissues.
