Where does the carbon in the carbon dioxide you breath out come from?

The Carbond Dioxide (CO2) in expired air is the waste product of complete cellular respiration that is carries in the blood to be removed by the lungs. Each cell uses a carbon based fuel (like glucose) to get energy. The cells that contain strucutres called Mitochondria are able to cully oxidise such hydrocarbons to just CO2 and water. The oxygen comes from inhaled air, and both the hydrogen and carbon comes from these food molecules.

∙ 12y agoThis needs alot of explaining.
The oxygen goes throught your mouth, wind pipe into your lungs.
First of all there are the lungs. When oxygen comes into your lungs there are these small bubble like things that have a thin wall. Outside of the thin wall there are blood vessels going to your cells. When the oxygen comes inside it goes throught the thin walls and mixes with the blood.
The blood then takes it to your cells and it reactes with the glucose in your cells. It produces CARBON DDIOXIDE, water and energy.
( glucose + oxygen = carbon dioxide + water +energy )
Then the carbon dioxide mixes with the blood and goes back to the lungs. It goes throught the walls of the bubble like things ( alviolai) and go back through your wind pipe and out of your mouth.
That's what happens....................

∙ 12y agoCarbon dioxide moves in and out of the atmosphere, the oceans, animals, trees and the soil as part of the carbon cycle, which neither creates nor destroys carbon. Additional atmospheric carbon dioxide comes from the burning of fossil fuels (coal, oil and natural gas). This burning releases carbon that has been safely stored underground for 300 million years.

What do you breath in?
we breath in oxygen and breath out carbon dioxide.
Is carbon dioxide useful and why?
yes. plants breath in carbon dioxide and then breath out oxygen for other living creatures. then we breath in that oxygen and breath out more carbon dioxide for the plants. basically, we could not survive without plants.
What role do carbon dioxide play in the carbon dioxide oxygen cycle?
animals and people breath out carbon dioxide and plants use carbon dioxide
How does carbon dioxide get from the air and into your body?
You breath it in.
Is carbon dioxide good for humans?
Carbon dioxide is a very useful and largely used chemical; carbon dioxide is not toxic but also doesn't maintain the life.
How does the spiny lobster obtain oxygen and give off carbon dioxide?
When lobsters are underwater they breath in oxygen, when they come above water they breath out carbon dioxide.
What do you breath in?
we breath in oxygen and breath out carbon dioxide.
Are high levels of carbon dioxide bad?
well, you don't breath carbon dioxide, you breath oxygen
Is carbon dioxide useful and why?
yes. plants breath in carbon dioxide and then breath out oxygen for other living creatures. then we breath in that oxygen and breath out more carbon dioxide for the plants. basically, we could not survive without plants.
Where does the carbon dioxde used by plants come from?
Humans inhale oxygen, and breath out carbon dioxide. It is like a cycle.
How are plants different than humans?
the Photosynthesi does not allow the ability of a plant cell to prouduce solar energy in carbon dioxide
Where does most of the air huumans breath come from?
They come from plants. It is a cycle. (Carbon Dioxide and Oxygen Cycle) When you breathe out you realse Carbon Dioxide and the plants sucks it in and relase oxygen and that is what we breathe in.
How does plants get the carbon dioxide?
Plants get carbon dioxide from the air we exhale. We breath out carbon dioxide and plants give us oxygen. So when we breath oxygen the air that we exhale is carbon dioxide that goes to plants.
How do fish breathe in and breathe out?
Yes they do. Its part of the carbon cycle. When plants give off carbon dioxide, animals breath it in, when they die, scavengers eat them then decomposer breaks the dead carcasses back into the basic materials.
Is the carbon dioxide you breath same with the carbon dioxide in soft drinks?
Yes it is.
Do lions breath in carbon dioxide?
As there is a low level of carbon dioxide in the air that animals (and people) breath, yes every breath taken in breaths in some carbon dioxide.But as carbon dioxide in the blood is transferred to the air in the lungs, increasing the level of carbon dioxide in that air, when they breath out both the carbon dioxide breathed in and the additional carbon dioxide from the blood are breathed out. Thus in balance more carbon dioxide is breathed out than is breathed in.
Do trees help the earth?
they breath out oxygen for the humans and breath in carbon dioxide which helps the earth have less carbon dioxide
