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.
73) The Haldane Effect says that it is easier for CO2 to bind to hemoglobin once oxygen has dissociated from the heme group.

- What is the biological advantage to the sigmoidal binding curve of hemoglobin for oxygen? A. It ensures that hemoglobin has a high affinity for oxygen. B. It allows hemoglobin to bind oxygen irreversibly. C. It ensures that hemoglobin can bind oxygen only weakly. D. It allows hemoglobin to shift between low and high affinities for oxygen.arrow_forwardDraw an oxygen-hemoglobin dissociation curve.

- What is the role of hemoglobin? A) It picks up CO2 and distributes it to the body B) It picks up O2 and distributes it to the body C) It picks up PO2 and distributes it to the body D) It picks up Hb and distributes it to the bodyarrow_forwardWhat would be the consequence of a deficiency of hemoglobin in our bodies?arrow_forwardYou 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?arrow_forward
- 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.arrow_forwardMyoglobin levels are higher in Tibetans and other ethnic groups that live at high altitudes. Explain the benefit of higher myoglobin levels for individuals living at high altitudes.arrow_forwardWhich statement describes hemoglobin's cooperativity? A. When tetrameric hemoglobin binds one molecule of O2, its shape changes to make it bind more readily to a second molecule of O2. B. When tetrameric hemoglobin binds one molecule of O2 its shape changes, which prevents binding of any more O2 molecules. C. When oxygen is present in the blood, the shape of hemoglobin changes to allow oxygen to bind to it. D. When the oxygen concentration in blood decreases, then hemoglobin changes its shape to retain oxygen more readily. E. None of the above answer choices correctly describes cooperativity.arrow_forward

What effect would an increased concentration of 2,3-BPG have on the oxygen-binding curve for hemoglobin? Why would this adaptation be beneficial for functioning well at high altitude?arrow_forwardThe following graph shows partial saturation (Y) of myoglobin (Mb), adult hemoglobin (HbA) and fetal hemoglobin (HbF) as a function of partial oxygen pressure (in mmHg). Use it to answer the question: Fetal hemoglobin ( biological function: HbF) demonstrates lower p50 than adult hemoglobin (HbA). This adaptation has the following A. Allow fetal hemoglobin form pentamer subunits. B. HbF has lower affinity for for O2 compared to adult Hb C. Allow fetal hemoglobin to effectively intercept oxygen from mother's hemoglobin. D.
