Hydrogen bonds with oxygen tightly during cellular respiration because oxygen is more electronegative than hydrogen. Oxygen has a greater attraction for electrons, which allows it to pull the shared electrons in a bond closer to itself. As a result, oxygen develops a partial negative charge, while hydrogen develops a partial positive charge. This unequal distribution of charges leads to the formation of hydrogen bonds, which are relatively strong.
