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.

When deoxyhemoglobin binds to oxygen it becomes oxidized hemoglobin?

False


What is the difference between deoxyhemoglobin and oxyhemoglobin?

Deoxy no oxygen and is purple. Oxy is with oxygen and is bright red color


When hemoglobin is not bound to oxygen it appears blue?

When hemoglobin is not combined with oxygen, it appears dark red.


What is the color of deoxyhemoglobin?

Dark red, almost burgundy. But the vein that carries the RBC filled with deoxyhemolgobin looks bluish because of the venous tissue, not deoxyhemoglobin.


What color is 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.


What is the difference in color in oxyhemoglobin and deoxyhemoglobin?

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.


What is the difference between deoxyhemoglobin and reduced hemoglobin?

Reduced hemoglobin does not have the oxygen molecules that oxyhemoglobin has. :)


Why deoxyhemoglobin is blue colour?

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.


How many oxygen molecules bind to myoglobin?

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.


How much oxygen does one gram of hemogloblin bind with?

What does hemoglobin bind with?

Mostly oxygen.


How is oxyhemoglobin and deoxyhemoglobin act as a buffer?

Oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) play a critical role in buffering blood pH by binding to hydrogen ions (H+) and carbon dioxide (CO2). When tissues produce CO2 during metabolism, it diffuses into the blood, where it can lead to an increase in H+ concentration and a decrease in pH. Hemoglobin can bind to excess H+, reducing acidity, and when it releases oxygen in tissues, it can also pick up CO2, forming bicarbonate, which further helps to stabilize pH levels. This buffering capacity is vital for maintaining acid-base balance in the body.
