explain......the oxygen capacity of hemoglobin?

Question

please quickly and aclear short answer

Answer 1

Short and sweet

1.) Each Hemoglobin can carry four oxygen molecules

2.) The binding of one oxygen molecule to hemoglobin induces a conformational change to make it easier for the next oxygen molecule to bind, which makes it easier for the third, which makes it easier for the fourth.

3.) Similarly, with a full hemoglobin, after the first oxygen is released, it's easier for the second one to come off and so on. This phenomenon is why all the oxygen isn't released into the tissue right after it leaves the heart.

4.) Look both ways when crossing the street.

Answer 2

the hemoglobin molucule has an affinity for oxygen. It binds to the oxygen and is carried through the blood stream to the tissues that need it.
Hemoglobin’s primary function is to bind oxygen that diffuses into the bloodstream from the lungs and then transport it to outlying tissues where it is released primarily for aerobic respiration. Hemoglobin (Hb) has to the capacity to bind between 1 and 4 oxygen molecules, ranging from fully "desaturated"- no oxygen Hb (deoxyHb) to fully "saturated" Hb (oxyHb)

Answer 3

The red of red blood cells,hemoglobin, carries oxygen chemically by becoming oxyhemoglobin. It can also carrie carbonmonoxide, as carboxyhemoglobin. This significantly decreases the ability to carry oxygen, as it does not let go of it at the cells. A hematocrit measures the amount of hemoglobin carrying cells in the blood. Low level would not carry as much O2.
