Content Objective: Explain how hemoglobin works using the oxygen dissociation curves.
Language Objective: Using a graph of the oxygen dissociation curves annotate what is happening at different parts.
Book Reference: p.p.754-765
Syllabus Details:
Oxygen dissociation curves show the affinity of hemoglobin for oxygen.
Fetal hemoglobin is different from adult hemoglobin allowing the transfer of oxygen in the placenta onto the fetal hemoglobin.
Oxygen dissociation curves show the affinity of hemoglobin for oxygen.
The Bohr shift explains the increased release of oxygen by hemoglobin in respiring tissues.
Carbon dioxide is carried in solution and bound to hemoglobin in the blood.
Carbon dioxide is transformed in red blood cells into hydrogen carbonate ions.
Chemoreceptors are sensitive to changes in blood pH.
Application: pH of blood is regulated to stay within the narrow range of 7.35 to 7.45. Skill: Analysis of dissociation curves for hemoglobin and myoglobin.
Application: Consequences of high altitude for gas exchange
