How is the oxygen in the atmosphere replaced?
Through oxygen cycle. Humans and animals take in oxygen and give out carbon dioxide. Plants take in carbon dioxide and give out oxygen. This ways the oxygen is circulated in the atmosphere.
What equation represents photosynyhesis?
Carbon Dioxide + Water ---->Glucose + Oxygen
The respiratory quotient is?
The ration of the carbon dioxide produced to the volume of oxygen consumed
When does oxyhemoglobin form?
Oxyhaemaglobin is an unstable molecule in the blood stream. On breathing in air( oxygen) oxygen combines with hemaglobin to form oxyhemaglobin. It is then transported around the body to the point of usage (muscle movement ), whereupon, it discharges the oxygen component to combines with carbon dioxide, formed from muscle activity. It is now carboxyhemaglobin, and is transported back to the lungs , where the carbon dioxide is discharged/(uncombined) , and more oxygen is re-combined. Such are the subtlties of hemaglobin it will combined and discharge oxygen and carbon dioxide., as part of the normal respiritary physiological process. However, if carbon MONOXIDE(CO) is breathed in this process between oxygen and carbon DIOXIDE (CO2) is broken. So no more oxygen can be breathed in or carbon dioxide breathed out. Hence Carbon Monoxide poisoning. Carbon Monoxide is a very powerful LIGAND. There is only one oxygen atom difference between CO & CO2 , but it makes all the difference between normal functioning and 'death'. Hemaglobin is a very large molecule, with iron(III) (Fe^(3+)) at the centre of the porphyrin ring, and there is a very subtle interplay between electrons in this molecule that allows the oxygen and carbon dioxide, to combine and discharge. Iron in oxidation state 'III' is a RED/Brown ion, hence the colour of blood.
What is the ratio of the gases in the atmosphere?
The ratio is approxNitrogen : Oxygen : Argon : Carbon Dioxide :: 39000 : 10500 : 465 : 19.
