How is hemoglobin's affinity for oxygen affected by the presence or absence of oxygen? rank hemoglobin molecules with the described conditions from most likely to bind oxygen molecules to most likely to release oxygen molecules. (for approaching this problem, open hint

Hemoglobin is a protein-rich in iron that has an affinity (combining ability) to oxygen and with oxygen, it forms oxyhemoglobin in red blood cells. The amount of hemoglobin in normal blood is 15 grams per 100 ml of blood, and the hour is usually called "100 percent".

Hemoglobin is a substance found in red blood cells. Hemoglobin is actually a globular protein in the form of 4 subunits, and each subunit contains hame.

Hemoglobin plays an important role in oxygen transport as long as it can re-bind oxygen. Hemoglobin tends to bind oxygen when the environment is full of oxygen and releases oxygen in a relatively low oxygen environment. This means hemoglobin takes oxygen in the lungs and releases it to tissues such as active muscle. In people who have normal hemoglobin, the capacity of the blood carries about 20 mL of oxygen per 100 mL of oxygen. In almost all situations, blood contains a lot of oxygen as it moves through the lungs.

Hemoglobin is carried by circulating red blood cells (erythrocytes). This circulation rotates for about 10 days containing approximately 3 x 10 red blood cells. A rough estimate of blood hemoglobin levels can be obtained from the amount of hematocrit or from the amount of blood by consuming each red blood cell that has normal hemoglobin

The heat produced by the metabolism reaction of muscle contractions releases a lot of acid & heat causes the body temperature to rise and the active cells need a lot of O2 to spur the release of O2 from OxyHb (Hb affinity towards O2 decreases) the curve shifts to the right.

Hypothermia causes slow cell metabolism so that the O2 needed by the tissue to release a small amount of O2 from Hb is also slow (Hb affinity for O2 decreases) and the hemoglobin oxygen dissociation curve shifts to the left.
