A low partial pressure of oxygen promotes hemoglobin binding to carbon dioxide. This is an example of the ________. Haldane effect Bohr effect Daltons law Henrys law
A developing fetus gets oxygen from its mothers blood. Fetal capillaries run through pools of maternal blood in an organ called the placenta. As fetal blood runs through these capillaries, it exchanges substances with the maternal blood around the capillary. The hemoglobin made by a fetus is different than that made after birth. Fetal hemoglobin binds oxygen more strongly at low oxygen levels than normal hemoglobin. How would fetal hemoglobins somewhat higher affinity for oxygen benefit the fetus?
Of the following, which does not explain why the partial pressure of oxygen is lower in the lung than in the external air? Air in the lung is humidified; therefore, water vapor pressure alters the pressure Carbon dioxide mixes with oxygen Oxygen is moved into the blood and is headed to the tissues Lungs exert a pressure on the air to reduce the oxygen pressure.
When a person develops a fever, which of the following statements hemoglobin saturation are correct? - Modify the structure of hemoglobin and decrease its affernity for O2 - Can shift the O2-hemoglobin dissociation curve to the right - Decrease O2 unloading occurs in the tissue - Modify the structure of hemoglobin and increase its affernity for O2 - Can shift the O2 hemoglobin dissociation curve to the left - Enhance O2 unloading occurs in the tissue
Hemoglobin will bind oxygen and release CO2 in places where there is a higher concentration of O2, lower concentration of CO2, lower temperature and lower acidity (as it is in lungs) and will do the reverse – release oxygen and bind CO2 - in places where there is a lower concentration of O2, higher concentration of CO2, higher temperature and higher acidity (as it is in working muscles). True False While white blood cells never leave the circulation, red blood cells regularly leave it and travel by lymphatic system or find home in other tissues, e.g., lymph nodes, spleen, etc. True False Blood clotting (coagulation) is a complex process involving many factors and it exhibits positive feedback loops: many of the factors also stimulate production of their own precursors. B lymphocytes mature in the thymus while T lymphocytes mature in the bone marrow True False Antibodies are molecules on the surfaces of foreign…
Which of the following situations occurs if a person's blood becomes more alkaline? A. Hemoglobin molecules retain less oxygen per heme group under alkaline conditions than they do at neutral pH or under acidic conditions. B. Hemoglobin molecules give up oxygen more readily under alkaline conditions than they do under neutral pH or under acidic conditions. C. Hemoglobin molecules change shape and begin to lose oxygen molecules. D. Hemoglobin molecules retain oxygen more readily under alkaline conditions than they do at neutral pH or under acidic conditions. E. There is no change in hemoglobin's oxygen-binding affinity under alkaline conditions when compared to blood at neutral pH or under acidic conditions.
Which of the following statements is FALSE regarding a leftward shift in the hemoglobin-oxygen dissociation curve? A) Affinity for oxygen is increased. B) Oxygen loading onto the hemoglobin is increased. C) Hemoglobin is more saturated at a given PO2. D) It can be caused by a decrease in temperature. E) It can be caused by a decrease in blood pH.
Which of the following statements is FALSE regarding a rightward shift in the hemoglobin-oxygen dissociation curve? A) Affinity for oxygen is increased. B) Oxygen loading onto the hemoglobin is increased. C) Hemoglobin is more saturated at a given PO2. D) It can be caused by a decrease in temperature. E) It can be caused by a decrease in blood pH.
How does the concentration of 2,3 BPG affect hemoglobin's P50 for oxygen? select the correct answer A) BPG binds to the N-terminus of Hemoglobin's alpha 2 subunit and increase hemoglobin's P50 for oxygen. B) BPG binds to the heme blocking oxygen's ability to bind and lowering hemoglobin's P 50. C) As the BPG increases hemoglobin's P50 for oxygen increase. D) As the BPG increases hemoglobin's P50 for oxygen decreases. E) BPG does not affect hemoglobin's P50 for oxygen
In carbon monoxide (CO) poisoning, CO binds to the heme of hemoglobin much tighter than oxygen (O2). What effect will this have on the ability of the tissues to get oxygen? Group of answer choices There will be no effect. CO will deliver oxygen to the tissues. Hemoglobin will bind more O2 and deliver more oxygen to the tissues. More hemoglobin will be produced to deliver oxygen to the tissues. Hemoglobin will bind less O2 and deliver less oxygen to the tissues.
Which of the following concerning hemoglobin is true? a) BPG decreases at high altitudes and causes more O2 offloading in tissues b) As pH increases, [CO2] increases in tissues, causing more O2 release in tissue c) The R state is stabilized by CO2 binding, whereas the T state is stabilized by O2 binding d) About 38% of oxygen dissociates from hemoglobin in tissues e) Hemoglobin has a higher affinity for oxygen than carbon monoxide My guess is D.
