What is the chemical equation in breathing (inhaling and exhaling)?

Question

Pls help me explain the breathing process through chemical aspect its for my chemistry subj tnx

Answer 1

you exchange the ligands CO2 for O2 on the molecule hemoglobin

here's a couple of links

http://en.wikipedia.org/wiki/Hemoglobin
https://sharepoint.cisat.jmu.edu/isat/klevicca/Web/isat454/hemoglobin_essay.htm
http://www3.interscience.wiley.com:8100/legacy/college/boyer/0471661791/structure/HbMb/hbmb.htm

the last ones the best..

but you should probably google hemoglobin reactions for yourself...

Answer 2

there is no 1 equation
becz breathng occurs in several phases

wen air goes inside r lungs
it is pickd up by the blood by an protein called homoeglobin
n it becomes oxyhaemoglobin

n then later haemoglobin releases oxygen at the organs n picks up carbon dioxide n becomes carboxyhaemoglobin


o2+ haemoglobin = oxyhaemoglobin

n co2 + haemoglobin = carboxyhaemoglobin

only this bit is the chemical phase everythng else is the physical phase iin breathing

Answer 3

The chemistry which happens in the lungs is very complex. It involves more than just Oxygen gas binding to hemoglobin.

Gas exchange takes place in the alveoli (plural), which are the the tiny saclike structures in the lungs at the end of the airways. The blood is pumped from the heart to the capillaries on the surface of these alveoli.

Inhaling involves the reaction of the Hemoglobin (Hb) in the red blood cells to with the Oxygen gas (O2) from the air to form Oxyhemoglobin (Hb-O2). Once the red cells are delivered to the internal cells of the body, the Oxygen is released by Carbon dioxide (and H+), which are in high concentration.

Hb-O2 (s) + CO2 (g) --> Hb-CO2 (s) + O2 (g)

Some of the Oxygen gas is not replaced. The Oxyhemoglobin becomes Deoxyhemoglobin

Hb-O2 (s) --> Hb (s) + O2 (g)

The blood is then pumped back to the lungs where the reverse reactions take place.

Hb-CO2 (s) + O2 (g) --> Hb-O2 (s) + CO2 (g)

Hb (s) + O2 (g) --> Hb-O2 (s)

The Carbon dioxide is then exhaled from the lungs.

You should notice that the Oxygen and the Carbon dioxide do not bind to the hemoglobin at the same site.

In addition, the pH of the blood is regulating these gas exchanges. The change of pH is do to a reversible reaction of Carbon dioxide with water.

H2O (l) + CO2 (g) <==> H2CO3 (aq)
and
H2CO3 (aq) <==> H+ (aq) + HCO3- (aq)

Answer 4

I think you mean respiration rather than breathing. That equation is:

Glucose + Oxygen => Carbon Dioxide + Water + Energy

Breathing is the process whereby oxygen enters the lungs, whereas respiration is the process where the oxygen produces energy.

Answer 5

oxygen+glucose=energy+water+carbon dioxide
When you breathe in air you take in oxygen which reacts with glucose and provides your body cells energy. Now, the formula above in chemistry can be written as:
O2+C6H12O6=energy+H2O+CO2
