"Webb5 juni 2024 · We can always get oxygen from the air by breathing, but one has to find oxidizable fuel (food). As such, we find it convenient to associate all of the energy of the reaction to the fuel, for bookkeeping purposes. But that's just bookkeeping. We do this because, if we're short on oxygen, we just have to breathe a little more. " - The oxygen we breathe originates from the

An oxygen molecule (the smallest amount of a chemical substance that can exist without further breaking down) is composed of two oxygen atoms, called O2. Oxygen and Its Role in Life

WebbOxygen (O₂) and carbon dioxide (CO₂) are essential gaseous components in our blood. When we breathe in, oxygen from the air enters our alveoli, where it is exchanged with carbon dioxide. This originates from metabolism, where bundled carbon is absorbed via food and released as carbon dioxide via the breath.

WebbTo shed light on this, statements such as “the ocean provides 50% of the oxygen we breathe”, or its equivalent, “every second breath we breathe comes from the ocean”, have become common mantras to highlight human dependence on the ocean and the risk of lower oxygen supply due to climate change and environmental degradation. WebbNatural abundance. Oxygen makes up 21% of the atmosphere by volume. This is halfway between 17% (below which breathing for unacclimatised people becomes difficult) and 25% (above which many organic compounds are highly flammable).
