How carbon dioxide in important in respiration?

CO2 is expired because when you expire your diaphram moves in and up decreasing lung volume, thus increasing the concentration of CO2 in the lungs. Then diffusion naturally occurs and the CO2 is expired and O2 is then inspired.


Does exhaled air contain more carbon dioxide or oxygen?

Carbon dioxide.


What causes the drop in the amount of oxygen between inspired and expired air?

During expiration, the air in the lungs has already been used for gas exchange in the alveoli, leading to a decrease in oxygen and an increase in carbon dioxide levels. This results in the drop in the amount of oxygen between inspired and expired air.

Does carbon contain carbon dioxide?

Carbon itself is a chemical element that exists in various forms like graphite and diamond. Carbon dioxide, on the other hand, is a compound made up of one carbon atom and two oxygen atoms. So, carbon itself does not contain carbon dioxide, but it can combine with oxygen to form carbon dioxide.

Why are carbon dioxide and carbon monoxide are not example of organic chemistry?

Carbon dioxide and carbon monoxide are not examples of organic chemistry because they do not contain hydrogen atoms bonded to carbon atoms. Organic chemistry focuses on compounds that contain carbon-hydrogen bonds, whereas carbon dioxide (CO2) and carbon monoxide (CO) consist of carbon atoms bonded to oxygen atoms instead.


What percentages of inspired air are oxygen and carbon dioxide?

Ambient air (the air you breathe in) contains about 21% oxygen and about 380 ppm carbon dioxide. This changes slightly summer to winter, downwind of green vegetation during the day and in buildings.
