Water is an important solvent in which metabolic reactions occur
Water dissolves substances inside cells. This allows the chemical reactions that keep organisms alive to take place.
Real World
In an athlete's bloodstream, glucose, amino acids, and mineral ions all dissolve in the plasma's water content — allowing them to be transported and react with enzymes at target tissues.
Exam Focus
When explaining water as a solvent, always mention polarity and hydrogen bonding as the structural reason — not just that 'water dissolves things'.
