Oxygen binds to the Fe(II). This causes a shift of the Fe(II) to be in plane with the porphyrin ring and it pulls the His in, which all increase the oxygen affinity.
False
Deoxy no oxygen and is purple. Oxy is with oxygen and is bright red color
When hemoglobin is not combined with oxygen, it appears dark red.
Dark red, almost burgundy. But the vein that carries the RBC filled with deoxyhemolgobin looks bluish because of the venous tissue, not deoxyhemoglobin.
Deoxyhemoglobin is a dark red or maroon color. It appears this way because it lacks oxygen, which gives it a more bluish or purplish hue when bound to hemoglobin.
Oxyhemoglobin is bright red in color, while deoxyhemoglobin is darker, more bluish-red in color. This difference is due to the presence of oxygen in oxyhemoglobin, which gives it its bright red color.
Reduced hemoglobin does not have the oxygen molecules that oxyhemoglobin has. :)
Deoxyhemoglobin appears blue because it reflects more blue light due to the absence of oxygen bound to the iron in its structure. The iron in deoxyhemoglobin results in a different electronic structure that absorbs less red light and reflects more blue light, giving it a bluish color.
1 Each myoglobin molecule has one heme group and can bind one oxygen molecule. Hemoglobin on the other hand can bind up to 4 molecules of oxygen.
One gram of hemoglobin can bind with approximately 1.34 milliliters of oxygen.
Mostly oxygen.
The cooperativity effect in hemoglobin allows it to efficiently bind and release oxygen by enabling one oxygen molecule to bind to one subunit of hemoglobin, which triggers a conformational change in the protein structure that makes it easier for other oxygen molecules to bind. This cooperative binding and release mechanism helps hemoglobin efficiently transport oxygen throughout the body.
