Why is it a good idea to have a carbon monoxide detector?
Carbon monoxide is toxic because it binds very tightly with haemoglobin to form carboxyhaemoglobin, thus inhibiting the oxygen carrying property of haemoglobin which is supposed to form oxyhaemoglobin reversibly with oxygen. Thus it can kill us as oxygen cannot be transported in our red blood cells. Carbon monoxide is a colourless, odourless gas, so it is a good idea to have a carbon monoxide detector in places where this gas may be emitted.
What is oxygen a solid liqid or gas?
Oxygen is a gas.
Which is not a compound water carbon dioxide gas silicon dioxide oxygen gas?
Oxygen gas is made up of one substance = oxygen. So oxygen gas is not a compound
Is oxygen a type of gas?
Oxygen is an element. At room temperature, molecular oxygen (O2) is a gas.
How do you identify oxygen gas?
By chemical analysis; also a candle burn in oxygen (or in a gas containing oxygen) but not in nitrogen, argon, carbon dioxide.
Why is some blood bright red?
because of the presence of oxygen gas in the haemoglobin of the red blood cell.
What are the major gases involved in circulation and respiration?
oxygen and carbon dioxide ('O' and 'CO2') . We breath in oxygen and breath out carbon dioxide (the unwanted gas). Oxygen is used is transported through the blood stream (haemoglobin) tis the main gas in circulation.
Can carbon monoxide damage the heart?
Haemoglobin ensures the oxygen carrying property of red blood cells. Usually, four oxygen molecules can reversibly bind with one haemoglobin molecule in red blood cells. Oxygen is thus transported around the body in the circulatory system.Hb + 4O2 ⇌ Hb(O2)4Note: Hb is haemoglobin; Hb(O2)4 is oxyhaemoglobinCarbon monoxide binds very tightly to haemoglobin in red blood cells to form carboxyhaemoglobin, thereby preventing haemoglobin from binding with oxygen to transport oxygen. Therefore carbon monoxide is toxic and can kill people. It does not really "damage the heart" so to speak, but it does prevent the circulatory system from performing its function.Carbon dioxide binds to the red blood cells better than oxygen does, and your body does not get enough oxygen and you suffocate to death.Carbon monoxide is a toxic gas. In high concentrations can be lethal.
How does carbon monoxide behave as a toxic gas?
Carbon monoxide is produced by incomplete combustion of hydrocarbons. Haemoglobin in your blood is not a stable compound, such that it can transport oxygen around your body. What carbon monoxide does is to react with the haemoglobin to form carboxyhaemoglobin, which is a stable compound, and you wouldn't get enough oxygen, which then you die of asphyxiation (if I didn't forget anything).
Why hemoglobin is better long distance oxygen transporter than myoglobin?
Both Myoglobin and Haemoglobin binds to oxygen, but they differ in many aspects. Usual site: Myoglobin: muscle tissues Haemoblogin: red blood cells (whole body) Main function: Myoglobin: stores oxygen (in muscle tissues) Haemoglobin: Oxygenation of tissues (whole body) Waste (CO2) collection (whole body) gas exchange (lungs, tissues) Oxygen carrying capacity: Myoglobin: monomeric = one heme prosthetic group, one iron atom Haemoglobin: tetrameric = four heme prosthetic groups, four iron atoms. Structure Myoglobin: secondary and tertiary, no allosteric interaction Haemoglobin: quaternary structure, allosteric interaction, different affinity Affinity to oxygen Myoglobin: Oxidation (Fe2+ → Fe3+) prevents oxygen binding. Haemoglobin: requirement specific affinity: (gradually increasing in the lungs, . gradually decreasing at the tissues) Prefered binding Myoglobin: Carbon monoxide preferred to Oxygen. Haemoglobin: Oxygen, carbon dioxide While in cases of hugely increased demand, myoglobin releases oxygen for metabolism, but, in the long run haemoglobin is more suitable for the purpose.

What kind of gas does the left atrium carry?
The atrium does not carry gas. Blood flows through it. The blood in the left atrium is oxygenated.
How does hemoglobin function in respiration?
Hemoglobin is involved in transport of oxygen (as well as a small amount of CO2). Hemoglobin contains an iron molecule at the center; it is the site of oxygen binding. When we obtain oxygen through respiration, it binds to hemoglobin in the blood and is then transported throughout the body.
What takes oxygen into the blood?
Oxygen enters your blood stream in your lungs. Inside your lungs the air pipe branches into smaller pipes which branch a number of times eventually forming 'alveoli'. The great amount of braching increases the surface area so there is more area for oxygen excahnge to occur, making the process more efficient. In the alveoli the capillaries are very close to the surface, so close that the oxygen gas can move across the thin wall into the blood stream. This is facilitated by haemoglobin which attracts and bonds with oxygen molecules.
What causes carbon monoxide to get into the body?
Engine exhaust, grills, and cigarettes. Carbon monoxide is a gas that is produced from these subjects.
What is colorless poisonous gas called?
Carbon monoxide ( CO ) is very toxic by blocking oxygen transport in red blood cells very effectively (200 times more binding power to haemoglobin than oxygen molecules).
How the supply of oxygen by red blood cells to other cells in the body is disrupted by smoking?
By smoking you reduce the amount of oxygen carried in the bloodstream because one of the gases generated by the burning of the tobacco is carbon monoxide. This gas combines with the haemoglobin in the red blood cells in the same way that oxygen does. But when this happens the oxygen-carrying power is obviously reduced. This is why carbon monoxide is a poison.
