Why is good?
It increases the bloods affinity to oxygen and buffers carbonic acid in the blood.
Why is hemoglobin good?
It increases the bloods affinity to oxygen and buffers carbonic acid in the blood.
Do red blood cells have a reversible affinity for oxygen and carbon dioxide?
yes thy do
Which componet of blood is 90 percent water?
Blood plasma
Does hemoglobin's affinity for oxygen increase or decrease with exercise?
It decreases due to the increase in carbon dioxide in the blood. This causes more oxygen to be uploaded to the tissues
What is hemoglobin and what system is it found?
A chemical with an affinity for oxygen ... and it's found in red blood cells in the circulatory system.
A componet blood that lacks a nucleus and assists in blood clotting?
Platelets
How can the oxygen store in myoglobin be replaced after use?
Myoglobin has a very high affinity for oxygen, meaning it binds it very strongly. At very low oxygen concentrations in the cell, myoglobin releases its oxygen, despite the high affinity, simply because there are too few oxygen molecules around to rebind to the myoglobin when they are released naturally from the myoglobin (which usually occurs anyway). Once the oxygen concentration increases again, returning to normal, oxygen molecules will collide with myoglobin. The myoglobin, with its high oxygen affinity, will strongly bind any oxygen that meets it, replenishing myoglobin's oxygen storage very quickly. As myoglobin's affinity for oxygen is stronger the haemoglobin's, it will 'steal' oxygen from haemoglobin in the blood very easily, replacing its bound oxygen. This binding system serves to release oxygen when it is needed if blood oxygen levels are reduced (due to high levels of exercise), but replenishes the supply when oxygen levels begin to rise again.
How does inhaling carbon decrease the oxygen level in your blood?
Carbon monoxide, which has a higher affinity for hemoglobin in the red blood cell, displaces oxygen from the hemoglobin molecule, thus decreasing the oxygen level in the bloodstream, and reducing its delivery to the bodily tissues and cells.
How does carbon monoxide increase blood pressure?
it combines with haemoglobin forming the carboxyhaemoglbin thus which is alarge complex and affinity to the oxygen is lost leading to increase in blood pressure.
How is hemoglobin's affinity for oxygen affected by the presence or absence of oxygen?
Hemoglobin is a protein that is carried by red blood cells. Homoglobin needs oxygen to be carried by the cells. Without it, the body does not receive enough protein.
In an unventilated space carbon monoxide from smoke or car exhaust builds up in the blood combining with hemoglobin to form?
When CO is not ventilated it binds to hemoglobin, which is the principal oxygen-carrying compound in blood; this produces a compound known as carboxyhemoglobin. The traditional belief is that carbon monoxide toxicity arises from the formation of carboxyhemoglobin, which decreases the oxygen-carrying capacity of the blood and inhibits the transport, delivery, and utilization of oxygen by the body. The affinity between hemoglobin and carbon monoxide is approximately 230 times stronger than the affinity between hemoglobin and oxygen so hemoglobin binds to carbon monoxide in preference to oxygen. ~ Wikipedia.
