How does the body produce carbon dioxide?

Answer 1

Well carbon dioxide is produced when the body needs to make energy. It happens at the cellular level, in the mitochondria of the cell. This organelle takes marcomolecules, anything from lipids, sugars, and other substances, and breaks them down to form water and carbon dioxide. That is why the body creates urine and excels carbon dioxide. This whole process cannot occur without oxygen and that is why we need it to survive. The reason why we need oxygen is because it is the final electron acceptor in the electron transport chain.

Answer 2

Carbon dioxide (CO2) is produced by our cells in normal metabolism. When we run or do some strenous exercise, our body cells release carbon dioxide in large amounts. The CO2 leaves the cells and goes into the blood, and the blood takes it to the lungs to exchange it for oxygen.

Answer 3

Carbon dioxide is not produced in the air. It is produced on the ground, largely by the oxidation reduction (burning) of carbon rich organic matter, like forest fires. Animal exhalations and plant decay are other sources of carbon dioxide release. Saccharomyces, for example, digests maltose and fructose sugars and emits ethyl alcohol and carbon dioxide as byproducts.

A small amount of CO2 is vented from underground by volcanoes and fumaroles.

In more recent years CO2 emissions from human activity have begun to exceed those of natural sources, such as the burning of coal to produce electricity and automobile exhaust. Today humans emit about 100 times the amount of CO2 produced from within the earth.

Answer 4

We can produce Carbon dioxide(CO2) by =

Treating Carbonates or Bicarbonates with acids:

(CO3-2 or HCO3-) + H+ ----> H2O + CO2

Burning Carbon (with sufficient Oxygen):

C + O2 ----> CO2

Burning Hydrocarbons:

CxHy + O2 ----> CO2 + H2O

Burning Carbohydrates:

Cm(H2O)n + O2 ----> H2O + CO2

Decomposing Carbonates or bicarbonates by heat:

HCO3- ----> H2O + CO2 + CO3-2

CO3-2 ----> CO2 + O2-

Burning Alcohols, Ketones or Aldehydes :

ROH + O2 ----> CO2 + H2O

R(C=O)H + O2 ----> CO2 + H2O

R(C=O)R' + O2 ----> CO2 + H2O

Reducing some oxides of high-valent elements with Carbon monoxide:

Fe2O3 + CO ----> Fe + CO2

CuO + CO ----> Cu + CO2

Treating Oxalates with heat

C2O4-2 ----> CO2 + CO + O2-

And may more processes

Answer 5

We breath in fresh air, the body absorbs the oxygen and the carbon dioxide produced by internal organs is exhaled.

Answer 6

Through cellular respiration.

Answer 7

carbon reacts with oxygen to form CO2
