¿cómo se relaciona la química en el ser humano?

Chemistry is related to the human being because we must eat and breathe to stay alive.

Our bodies consist of molecules. Those in our cells use oxygen from the air to convert the food we eat into CO₂ and H₂O and release large amounts of energy.

These conversions are all chemical changes. On average, 37 × 10²¹ chemical reactions occur in the human body every second.
