Select ALL correct statements regarding myoglobin and hemoglobin.
Statements:
|
Myoglobin has a higher affinity for oxygen than hemoglobin does. |
|
|
Both myoglobin and hemoglobin contain mostly alpha-helical structures. |
|
|
Myoglobin has one binding site for 2,3-BPG. |
|
|
Hemoglobin is a tetramer, each of which binds one heme group. |
|
|
In both myoglobin and hemoglobin, iron ions (Fe2+) bind directly to oxygen. |
|
|
Myoglobin is a tetrameric protein. |
|
|
Hemoglobin exhibits cooperative binding with oxygen. Myoglobin does not. |
|
|
Hydrogen ion, carbon dioxide, and 2,3-BPG are negative allosteric effectors of oxygen binding to hemoglobin. |
|
|
Myoglobin has a lower P50 for oxygen than hemoglobin does. |
|
|
Hemoglobin has a higher affinity for oxygen than myoglobin does. |
|
