What happens to carbon dioxide during respiration?

Answer 1

Per glucose molecule, 2 moles of carbon dioxide are released during the link reaction of respiration when pyruvate is oxidised to acetyl coA and 4 moles are also released in the Krebs cycle when citrate is oxised to oxoloacetate. This is because each molecule of glucose is broken down into 2 molecules of pyruvate, each of which perform the link reaction and the Krebs cycle.

Answer 2

Normally, carbon dioxide is taken in by plants and released as oxygen. Us humans (and any living thing) breathes in this oxygen and breathes out carbon dioxide, once again taken in by the plants. This is called the carbon cycle.

The equation for cellular respiration is: C6H12O6 (glucose) + 6O2 ------> 6CO2+6H2O. :)

HOWEVER, these days, humans have been the main problem in the situation of 'Global warming'. With SO MANY sources like fossil burning (combustion) and oil spillage and much more, the earth's temperature is rising provoking Global warming.

An average of 29 million, 8 hundred thousand trees are cut down everyday around the world. As trees have a major role in the carbon cycle, more and more carbon dioxide, breathed out by us is left un-used in the atmosphere.

We need to stop OUR planet from suffering. I put 'our' in capitals because we must remind ourselves that this is where we are from, and if there is an end to the world, make it a happy one. No one likes dying in pain... The earth needs us and we're stamping all over it, make a difference :')

Answer 3

It will diffuse back into the blood where it will react with water forming bicarbonate ions which are more soluble than carbon dioxide gas. At the lungs it will convert back into its gaseous form, diffuse across the alveolar membrane and get exhaled with the next ventilation cycle.

Answer 4

It becomes a part of air and again utilized by plants in photosynthesis to make organic compounds.

Answer 5

Nothing, carbon dioxide isn't used in cellular respiration. Its a product of the Krebs cycle and when pyruvate is oxidized into Acetyl CoA.

Answer 6

it stays in your body for about an hour then it goes out into the air again

Answer 7

it is breathed out of the body by the lungs

Answer 8

you breath it out

Answer 9

It gets used throughout the plant
