combination of water molecules
Selitys
The reduction of oxygen (O₂) by hydrogen (H) is indeed responsible for the formation of water (H₂O) in tissue respiration, specifically during the final stage of cellular respiration known as oxidative phosphorylation.
You'll recall that in cellular respiration, glucose and other organic molecules are broken down to release energy in the form of ATP (adenosine triphosphate).
