Components in exhaled and inhaled air

We inhale air that is comprised of roughly 78 percent nitrogen and 21 percent oxygen, as well as a trace amount of other gases.

When we exhale, the components are the same, they just come out in different amounts. Exhaled air is made up of about 78 percent nitrogen, 18 percent oxygen, and four percent carbon dioxide, excluding those trace gases.

TL;DR

Inhaled: 78% Nitrogen, 21% Oxygen, 1% Other Gases

Exhaled: 78% Nitrogen, 18% Oxygen 4% Carbon Dioxide

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
