What else can I help you with?
Most of the oxygen in the blood is transported?
Oxygen molecules are bound to the red pigment HEMOGLOBIN, a protein complex found exclusively in red blood cells. A very small amount of oxygen is also dissolved in the liquid portion of blood, but hemoglobin carries the bulk of oxygen.
What kind of chemical is in your red blood cells that can pick up oxygen and carbon dioxide?
hemoglobin it contains Iron (Fe) which is why its important to get a source of iron in your diet Each hemoglobin can carry 4 oxygen molecules-if oxygen was not bound in hemoglobin the blood would not be able to have a high enough saturation to supply tissues Carbon dioxide does not use hemoglobin as much as oxygen and more carbon dioxide can be dissolved in the blood itself compared to oxygen Also using the bicarbonate buffer CO2 is converted into HCO3- which can be even more dissolved in the blood than CO2 alone
What blood cells help deliver oxygen into the body cells?
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the body's tissues and organs. Their main function is to transport oxygen bound to hemoglobin, a protein that gives blood its red color.
What iron - compound carries oxygen in the bloodstream?
Hemoglobin is the iron-containing compound that carries oxygen in the bloodstream. Each hemoglobin molecule can bind to up to four oxygen molecules, allowing for efficient transport of oxygen from the lungs to the body's tissues.
What brings oxygen into the body other than your lungs?
Oxygen is also transported into the body through the bloodstream by binding to hemoglobin in red blood cells. Hemoglobin carries oxygen from the lungs to tissues and organs where it is needed for various cellular processes.

What small molecules bind to hemoglobin?
Carbon dioxide and BPG bind to amino acids located on hemoglobin. Oxygen molecules bind to the iron molecules located in the heme. Each hemoglobin molecule can carry up to four oxygen molecules, one on each of the four iron molecules. Nitric oxide can also bind to hemoglobin when either oxygen or carbon dioxide are bound to the hemoglobin.
Does hemoglobin have proteins?
Hemoglobin is an iron-containing protein. Hemoglobin contains a hemo prosthetic group that has an iron atom at its center. When the iron is bound to oxygen, the hemo group is red in color (oxyhemogoblin), and when it lacks oxygen (deoxygenated form) it is blue-red.
The blood oxygen bound to hemoglobin is what?
Oxygenated blood is carried through the body by arteries. There is one exception though - the pulmonary artery carries de-oxygenated blood to the lungs; the pulmonary vein returns to the heart carrying oxygenated blood.
Is hemoglobin affected by pO2?
Yes, hemoglobin is affected by the partial pressure of oxygen (pO2). As pO2 increases, hemoglobin's affinity for oxygen also increases, facilitating oxygen binding in the lungs. Conversely, in tissues where pO2 is lower, hemoglobin releases oxygen more readily. This relationship is described by the oxygen-hemoglobin dissociation curve, which illustrates how hemoglobin's saturation with oxygen changes with varying pO2 levels.
What is the maximum o2 that can be carried in arterial blood?
The maximum amount of oxygen that can be carried in arterial blood is approximately 20.2 mmol/L. This is equivalent to about 98.5% of the oxygen that is dissolved in the plasma. The remaining 1.5% is bound to hemoglobin and is termed oxyhemoglobin. The amount of oxygen that can be carried by the blood is dependent on the concentration of hemoglobin in the blood as well as the oxygen saturation of hemoglobin. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment which is why the amount of oxygen that can be carried varies in different environments. The following factors affect the amount of oxygen that can be carried in arterial blood: Hemoglobin concentration Oxygen saturation of hemoglobin Partial pressure of oxygen in the environmentHemoglobin is a protein in red blood cells that binds to oxygen and carries it throughout the body. The concentration of hemoglobin in the blood is an important factor in determining how much oxygen can be carried. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment. This means that the amount of oxygen that can be carried in the blood varies in different environments. For example in a high-altitude environment where the partial pressure of oxygen is lower the oxygen saturation of hemoglobin is also lower resulting in less oxygen being carried in the blood.
What substance causes red blood cells to change coloour?
Hemoglobin changes color according to what it is bound to. When it is oxygenated, it is closer to bright red. When it is carrying carbon dioxide, it is darker red or brown. When it is carrying carbon monoxide, it is also quite bright red.
What is a Chemical in red blood cells that carries oxygen?
Hemoglobin is the protein in red blood cells that carries oxygen throughout the body. It binds to oxygen in the lungs and releases it to tissues in need. Hemoglobin also helps transport carbon dioxide waste back to the lungs for exhalation.
What contains hemoglobin?
The "unusual" element in hemoglobin is iron, but hemoglobin also contains carbon, hydrogen, oxygen, and nitrogen.

What determine whether blood is bright red or dull brick red?
The color comes from hemoglobin and the hemoglobin changes color depending upon what is bound to it. Oxyhemoglobin (hemoglobin with oxygen bound to it), deoxyhemoglobin (hemoglobin with no oxygen bound to it) is somewhat bluish. Arterial blood, which has been to the lungs and is on its way to the tissues, is usually fairly saturated with oxygen (anywhere from 95-100% of the hemoglobin is bound to oxygen), and so it looks bright red. Blood in the veins, coming back from the tissues, is less saturated (perhaps 60-80%), and so it appears darker. If there is enough unbound hemoglobin in the blood, it may actually take on a bluish hue, and that is why someone may appear blue if they are not getting oxygen. Carbon monoxide also binds to hemoglobin and results in an even brighter red color than when oxygen binds. Someone with carbon monoxide poisoning may have even brighter red blood and may have a bright red coloration to the lips and fingernails. It is also possible for the iron in hemoglobin to be changed from the ferrous (2+) to ferric (3+) state and the result is methemoglobin, which is a more brownish compound. There is normally a very small amount of methemoglobin circulating in the blood and this can be increased by exposure to certain chemicals (in particular, certain nitrogen compounds). Interestingly, methemoglobin is capable of binding cyanide, so the "antidote" for cyanide poisoning is a nitrogen compound that converts hemoglobin to methemoglobin, which then binds up free cyanide in the blood. Under normal circumstances, the blood contains primarily oxyhemoglobin and deoxyhemoglobin.
