A closer look
Your biology is casually utilizing the weirdest parts of quantum mechanics to keep you alive. In classical chemistry, an atom needs a specific amount of activation energy to cross a reaction barrier, much like a hiker climbing over a mountain. But enzymes involved in cellular respiration don't have time for hiking. Instead, because subatomic particles also act as waves, hydrogen atoms occasionally just teleport straight through the chemical mountain. Without this literal quantum tunneling accelerating these vital biological reactions, your cells would suffocate in their own metabolic sluggishness.
