What is the catalyst for much of the body's metabolism?

Explanation:
Water serves as the medium in which nearly all metabolic reactions take place. In the body's cells, chemistry happens in aqueous solutions, so water dissolves nutrients and ions, allowing enzymes and substrates to collide and react. It also participates directly in many reactions through hydrolysis and other water-involved steps, and it helps transport substances and regulate temperature to keep metabolism running smoothly. Although oxygen powers the energy-producing parts of metabolism and glucose acts as a fuel, water is the universal facilitator that enables the wide range of metabolic reactions to occur.
