Here's why:
* Specific heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a very high specific heat capacity, meaning it takes a lot of energy to change its temperature.
* Chemical reactions in cells can release or absorb heat. If a reaction releases heat, the water inside the cell will absorb that heat without significantly increasing its own temperature. Conversely, if a reaction absorbs heat, the water will release some of its stored heat to keep the temperature relatively stable.
* This ability of water to act as a heat buffer helps maintain a stable internal environment for cells, which is crucial for proper functioning of enzymes and other cellular processes.
